At least four national organizations are spending millions to unseat Republican state senators who voted against Trump's redistricting plan. The combined spending likely exceeds $4 million and could approach $7 million — dwarfing what state senate candidates can raise on their own by 10:1 or more.
The financial architecture is as significant as the dollar amounts. The two largest players operate through 501(c)(4) nonprofits that are legally exempt from donor disclosure. Voters in these districts cannot know who is funding the campaigns for or against their state senators.
