The NBC News account said three of the legislators who rejected the redistricting plan told NBC News on Wednesday they have “zero regrets,” including state Sen.

Greg Walker, state Sen.

Jim Buck, and state Sen.

Linda Rogers.

NBC News also reported that Walker lost to state Rep.

Michelle Davis, Buck lost, and Rogers was defeated by Brian Schmutzler, while Greg Goode advanced to the general election and Spencer Deery led Trump-backed Paula Copenhaver by just three votes in a race that remained too close to call Wednesday.

Money, threats, and clout

The fight over Trump’s endorsements in Indiana’s state Senate races was framed by the amount of outside spending and the pressure on incumbents, with Newsweek reporting that an estimated $9 million in advertising from national groups had been spent attacking the incumbents.

Newsweek also quoted Vice President JD Vance accusing Senate President Pro Tem Rodric Bray of deception, writing on X that “That level of dishonesty cannot be rewarded,” and it described Trump’s post on Truth Social calling the senators “SUCKERS” for the Democrats.

ABC News added that Trump endorsed seven primary challengers to Republican state senators up for reelection who voted against the redistricting, and it quoted Professor Emeritus Joshua Kaplan saying, “people are looking at this as a sign of as a test for the president's clout.”

NBC News described how the legislators saw the ad environment as coercive, quoting Jim Buck saying, “You tell a lie enough times, and it becomes the truth,” and it reported that Buck said roughly $1.3 million was spent on ads opposing him in his primary.

What comes next

NBC News said the mid-decade redistricting battle these lawmakers pushed back against has continued apace nationwide, adding that “Eight states have enacted new congressional maps over the past year.”

NBC News also reported that a major U.S.

Supreme Court ruling last week could pave the way for others to join them soon, while Walker said, “That’s how Congress functions or dysfunctions today.

It’s the threat of primaries.”

In Indiana, CBS News said Bray’s leadership position could be in jeopardy with the results of Tuesday’s election, and it quoted Bray telling CNN Tuesday that he had “no regrets” over the vote’s outcome.

NBC News further captured the lawmakers’ view of what is at stake, with Buck warning that “Dark money has really become an issue to deal with, but it’s the people are starting to lose their voice.”
