The Race
Indiana Senate District 45 is not competitive, and everyone involved knows it. Republican incumbent Chris Garten -- the Senate Majority Floor Leader, a Marine combat veteran, Trump-endorsed, and the author of the session's flagship legislation -- faces Democrat Nick Marshall, who lost to Garten by 24 points in 2022, and Libertarian Larry Mahaney, an EMT and first-time state-level candidate nominated at the Libertarian convention on March 22, 2026. [1]
Garten is unopposed in the Republican primary. Marshall is unopposed in the Democratic primary. The general election on November 3, 2026, is the only contest, and the structural math makes it a foregone conclusion. The question is not who wins SD-45. The question is what this race reveals about the man who holds it, the man who keeps running against him, and the district that connects Louisville's Indiana suburbs to the statehouse.
The District: Louisville's Back Yard
Senate District 45 sits on the Ohio River, directly across from Louisville, Kentucky. After the 2021 redistricting, it encompasses all of Clark County and portions of Floyd County -- specifically the eastern section of New Albany. [2] Key communities include Jeffersonville (the largest city, population approximately 50,000), Clarksville, Sellersburg, Charlestown (Garten's hometown), and portions of New Albany. The district's approximately 135,806 residents live in what is functionally the Indiana side of the Louisville metropolitan area. [3]
The 2021 redistricting reshaped this district significantly. Jeffersonville had previously been split between Districts 45 and 46; the new maps unified Clark County within District 45 and pulled in eastern New Albany from the old District 46, which was eliminated as a southern Indiana seat entirely and relocated to downtown Indianapolis. [2] Floyd County, which had been represented as a single unit for decades, was split between Districts 45 and 47. Critics, including council member Al Knable, argued the split would "lead to confusion among voters" and mismatch urban and rural interests. [2]
The partisan lean is clear. Garten won 62.7% in 2018 (a three-way race including a Libertarian) and 62.1% in 2022 against Marshall alone. [1] Before Garten, Republican Jim Smith held the seat from 2010 to 2018, though his margins were narrower -- he won 52.1% against Democratic incumbent James Lewis in 2010 and 53.8% in 2014. [1] Garten's consistent 62% floor reflects both the district's conservative lean and the advantages of incumbency in a metro-suburban seat where economic development, roads, and broadband matter more than ideology.
The Incumbent: Chris Garten (R)
Chris Garten is not a typical state legislator. At 44, he is the youngest person to hold the Majority Floor Leader position and the first to receive it in his first term -- appointed in August 2022 by Senate President Pro Tempore Rodric Bray. [4] He is, by any structural measure, the second most powerful Republican in the Indiana Senate.
Background and biography. Garten was born in Fort Lauderdale, Florida, in 1982, but grew up in Scottsburg, Indiana, in modest circumstances. He was adopted at age 14 after a childhood marked by parental alcoholism. He graduated from Scottsburg Senior High School in 2000 and enrolled at Indiana University Southeast, but left after September 11, 2001, to enlist in the Marine Corps Reserve. He served 14 years (2001-2021, with broken time), completed two combat deployments to Iraq -- in 2003 and 2005-2006 -- and separated as a gunnery sergeant. During his second deployment, he served as a platoon commander and scout team leader, participating in over 650 security missions. [4]
After returning from Iraq in 2007, he founded Signature Countertops, Inc. in a one-car garage in Jeffersonville. The company grew into what he describes as "an award-winning industry and market leader in natural stone surfacing." He did not complete his college degree until August 2023, using Indiana University Southeast's degree reclamation program. [4]
Legislative record. Garten has authored or co-sponsored over 80 bills that became law. [5] His 2026 session was arguably his most significant. Senate Bill 1, his flagship, imposed stricter eligibility verification for Medicaid and SNAP, reinstated work requirements for the Healthy Indiana Plan, and eliminated broad-based categorical eligibility for food stamps. It passed the Senate 38-8, the House 62-31, and was signed by the governor as Senate Enrolled Act 1 on March 4, 2026. The White House endorsed it as a "gold standard" for Medicaid reform. [6] He also authored Senate Enrolled Act 256, which restricts foreign adversary economic and land acquisitions in Indiana, and served as Senate sponsor for HEA 1001, a housing reform package. [5]
His committee portfolio -- Appropriations (Ranking Member), Rules and Legislative Procedure (Ranking Member), Joint Rules (Chair), and Tax and Fiscal Policy -- reflects his position at the center of the Senate's budgetary and procedural machinery. [5]
Redistricting and Trump. Garten voted yes on HB 1032, the Trump-backed congressional redistricting bill that failed 31-19 in December 2025. His floor speech was one of the most combative in the chamber: "The vote we are about to take is not simply procedural. It's not just about lines on a map. It's a vote of critical, epic proportion that will define Indiana's role in the recovery of this republic." He added: "Some will say these maps are political. Let me be clear, you're damn right they are." [7]
On March 25, 2026, Trump endorsed Garten for re-election on Truth Social, calling him "a true MAGA Warrior and America First Patriot" and praising his role as "Majority Floor Leader of the Indiana State Senate, and Brave U.S. Marine Corps Veteran." Garten received Trump's "Complete and Total Endorsement for Re-Election." [8] The endorsement was part of a batch of 17 given to Indiana Senate Republicans who had supported redistricting -- a reward for loyalty in a fight that failed.
Fundraising. Garten has raised $938,204 across his 2018 and 2022 cycles combined, a substantial war chest for a state legislative seat. [4] His 2026 fundraising figures are not yet publicly available in aggregate, but the leadership position guarantees access to party and PAC contributions at levels his opponents cannot match.
Awards and recognition. Garten has accumulated an unusual volume of institutional recognition: "Indiana Power 50" (2024, 2025), "Legislator of the Year" from the Indiana State Police Alliance (2023), Indiana Bankers Association (2022), and Disabled American Veterans (2022), "Senator of the Year" from Aviation Indiana (2022), and the "John C. Hart Presidential Award" from the Indiana Builders Association (2021). [5] This list reflects broad industry and institutional support -- banking, law enforcement, veterans, builders, aviation -- that translates into both fundraising capacity and grassroots credibility.
The Challengers
Nick Marshall (D)
Nick Marshall is running for the same seat, against the same opponent, for the second consecutive cycle. That decision -- to challenge a well-funded, Trump-endorsed Majority Floor Leader in a district he lost by 24 points -- deserves honest assessment.
Marshall's biography is genuinely compelling. He spent over twenty years in state care, beginning as an infant and recommitting at age eighteen. He was raised by two sets of foster parents -- "a veteran, a teacher, a farmer, and a caregiver." He became the first in his family to graduate from college, earning a bachelor's degree from the University of Louisville, where he was active in Phi Kappa Tau fraternity and served as the university's Cardinal bird mascot. He married his wife Melonie, whom he met at Louisville; they have two children, Sebastian and Evelyn. [9]
Professionally, Marshall works at Republic Bank and Trust and serves on multiple boards in the Kentuckiana region focused on foster youth and at-risk populations: the Coalition Supporting Young Adults, the Home of the Innocents advisory board, and the Nativity Academy of St. Boniface. He volunteers at The Cabbage Patch Settlement House and served on the One Love Louisville Implementation Team, a Metro Government violence reduction initiative. [9] [10]
His 2026 platform centers on four areas: fully funding public education (teacher pay, disability resources, early childhood), making life more affordable (lower taxes on working families, eliminating utility reconnection fees, restoring childcare vouchers), defending healthcare access (opposing Medicaid and Medicare cuts, addiction assistance, emergency reproductive care), and investing in community safety (returning SB1 revenue to local governments, modernizing drug prevention, increasing police/fire/EMS funding). [11]
That last point is strategically interesting. Marshall is explicitly campaigning against Garten's flagship achievement -- Senate Bill 1 -- arguing that its Medicaid and SNAP restrictions will drain revenue from local governments. His platform promises to "return those tax dollars lost from SB1 back to local governments, without raising taxes." [11] This is the closest thing the race has to a substantive policy debate: the Majority Floor Leader's signature bill versus a challenger who says it will hurt the communities it claims to protect.
The structural challenge is severe. In 2022, Marshall raised $16,520 and received 15,746 votes (37.9%). [1] [12] Garten raised roughly 57 times more across his career. Marshall's campaign infrastructure -- a website, social media accounts, podcast appearances on WFHB and Progressive Indiana -- is grassroots in the most literal sense. [10] [13] He has no major institutional endorsements surfaced in public reporting and no path to matching Garten's fundraising.
What Marshall does have is persistence and a story that resonates at the human level. A foster kid who became the first in his family to graduate college, who keeps showing up to advocate for children and families in a district where he knows the math is against him -- that is not nothing. Whether it translates into a meaningfully different margin in November 2026 is the empirical question.
Larry Mahaney (L)
Larry Mahaney is the Libertarian nominee for SD-45, selected at the Libertarian Party of Indiana's state convention in Fort Wayne on March 22, 2026. [14]
Mahaney's public footprint is minimal but consistent. He has lived in Jeffersonville since 2015 and has worked as an emergency medical technician in or near Clark County since 2016, including approximately one year at New Chapel EMS. Since 2020, he has taught courses in CPR, first aid, firearms safety, and active shooter prevention. [15]
His only previous candidacy was the 2024 race for Clark County Commissioner Board District 1, where he ran as a Libertarian against Republican incumbent Connie Sellers and Democrat Katie Morgan. [15] He did not complete Ballotpedia's candidate survey, and his campaign generated no significant media coverage. His platform for that race centered on government transparency -- demanding accountability, ending closed government meetings, and livestreaming County Commissioner sessions. [15]
Mahaney has not published a detailed state senate platform. His Ballotpedia profile for the 2026 race contains no biographical information. [14] For context, the 2018 Libertarian candidate in SD-45 (Charles Johnson) received 3.2% of the vote. [1] Mahaney's candidacy will likely perform in that range -- a presence on the ballot that offers voters a third option but does not alter the race's dynamics.
Why It Matters
Senate District 45 is not where Indiana's political power is contested. It is where Indiana's political power is manufactured.
Chris Garten is the youngest and most rapidly ascended leader in the Indiana Senate. He authored the session's most consequential and most controversial legislation. He voted for Trump's redistricting push with a floor speech that treated partisan map-drawing as a patriotic duty. He received a presidential endorsement in a race where he faces no primary and no serious general election threat. He has secured nearly $4 million in road-funding grants and over $18 million in rural broadband for his district. [5]
The endorsement is not about SD-45. It is about what Garten represents in the broader Indiana Republican ecosystem: a young leader who carries the Trump brand, who delivers legislative product aligned with the national MAGA agenda, and who holds a safe enough seat to do both without electoral risk. The endorsement rewards loyalty and signals to the rest of the caucus what alignment looks like.
For Marshall, the race is about something different. His platform directly challenges SB 1 -- the law that bears his opponent's name and carries White House approval. Whether Marshall can use that debate to close the gap even modestly would say something about whether Garten's policy choices carry local costs that the national endorsement cannot cover. In 2022, Marshall ran on foster care and education. In 2026, he is running on the consequences of his opponent's own legislation. That is a more targeted campaign, even if the structural arithmetic remains the same.
Mahaney's presence adds a third line on the ballot but does not change the calculation. In a district where the incumbent wins by 24 points, the Libertarian vote is a rounding error.
The race to watch in SD-45 is not the general election. It is what Garten does next. Majority Floor Leader at 44, with a legislative record, a Trump endorsement, military credentials, and a business biography -- this is a resume being built for a higher office. Whether that means a future run for Senate President Pro Tempore, a congressional seat, or something else entirely, the 2026 re-election is a stepping stone, not a destination.
