Trump’s Redistricting Retribution in Indiana: A Test of GOP Loyalty
5/8/2026, 8:27:18 PM
Core Event: Primary Upset of Anti-Trump Senators
On May 5 2026 Indiana Republicans held primaries in 13 state-senate districts. President Donald Trump endorsed challengers against seven incumbents who had voted against his proposed congressional redistricting plan. Five incumbents—Greg Walker (41st), Jim Buck (21st), Dan Dernulc, Travis Holdman (19th) and Linda Rogers (11th)—were defeated; one incumbent, Greg Goode (38th), won; a race between Spencer Deery and Paula Copenhaver remains too close to call.
Background & Context: Trump’s Mid-Decade Redistricting Push
In December 2025 the Indiana Senate, despite a 40-10 Republican supermajority, voted 31-19 to reject a map that would have added two GOP-leaning congressional seats by dismantling Democratic districts in Indianapolis and Gary. Trump publicly threatened to “primearied” any lawmaker who opposed the plan, labeling dissenters “RINOs,” and later posted on Truth Social urging supporters to back primary challengers.
Key Figures & Groups
President Donald Trump; Senate President Pro Tempore Rodric Bray (R), who opposed the map; anti-redistricting senators Greg Walker, Jim Buck, Dan Dernulc, Travis Holdman, Linda Rogers, Spencer Deery, Greg Goode; Trump-backed challengers Michelle Davis, Tracey Powell, Trevor De Vries, Blake Fiechter, Brian Schmutzler, Paula Copenhaver. Supporting organizations included Turning Point Action, Club for Growth, Hoosier Leadership for America, American Leadership PAC, and U.S. Sen. Jim Banks, who praised the results.

Why It Matters
The outcomes illustrate Trump’s capacity to shape intra-party contests, reinforcing his role as de-facto GOP leader despite low national approval. Success may embolden similar redistricting battles in other states and influence Republican strategy for the 2026 midterms.
Official Statements & Responses
Trump reiterated that dissenters “should be ashamed” and pledged to “primaried” them. Jim Banks said the night proved Trump is “the single most popular Republican among Hoosier voters.” Micah Beckwith framed the effort as a fight for the party’s future. Rodric Bray defended the Senate’s decision as “the right thing for Indiana.” Incumbents Walker, Buck and Rogers each asserted “zero regrets” about their votes.
Criticism & Opposition
Senators Buck and Rogers described the influx of “dark money” as silencing ordinary voters. Buck warned that “the people are starting to lose their voice.” Former state representative Mike Murphy condemned the president’s “RINO” labeling as authoritarian. Several lawmakers noted harassment, swatting threats, and a “rich man’s playground” of political spending.
Conflicting Reports & Gaps
Advertising expenditures are reported variously as $8.3 million, $9 million, $12 million, and $13.5 million, reflecting differing measurement scopes. The exact vote totals for Dan Dernulc’s district are not provided, and the final outcome of the Deery-Copenhaver race remains pending.
