Trump-Backed Republicans Challenge Incumbents in Indiana Primaries
Seven Republican state senators are seeking re-election against candidates endorsed by former President Donald Trump as Indiana voters head to the polls. This election serves as a critical test of political influence following resistance from some state lawmakers to Trump’s aggressive campaign to pressure them into redrawing congressional districts.
The primary vote has evolved into a statewide referendum on political retribution. Seven state senators who opposed Trump’s mid-decade redistricting effort now face challengers supported by the former president, who declared that “every one of these people should be ‘primaried’” after the redistricting push failed.
Trump-aligned dark money groups have invested over $7 million on television advertisements in Indiana this year, according to data from AdImpact. The majority of this spending targets lawmakers who allied with Democrats during the December redistricting vote.
Key Races and Candidates
Greg Goode, a first-term Republican representative from Terre Haute, is engaged in a competitive race in District 38 against city council member Brenda Wilson, who has received endorsements from both Trump and Indiana Governor Mike Braun. A third candidate, Alexandra Wilson—unrelated to Brenda Wilson—is also contesting the seat.
Goode opposed Trump’s redistricting initiative after hosting a public hearing where 71 individuals spoke against the proposed changes, with none in favor.
Incumbents Face Intense Challenges
Jim Buck, a state senator from Kokomo with 18 years in office, is also confronting a Trump-backed challenger.
“We’ve never had Washington meddle into our elections like they have this time,”
Buck stated.
“Now I’ve got over $1m against me in one race.”
One advertisement disparaged the 80-year-old senator by labeling him “old, pathetic, liberal.”
Political Landscape and Spending Patterns
Republicans currently hold seven of Indiana’s nine congressional districts, and the overall balance of power is expected to remain stable in the upcoming midterm elections. Trump’s redistricting plan aimed to dismantle Indiana’s first and seventh congressional districts, which cover the urban centers of Indianapolis and Gary, areas traditionally held by Democrats.
Spending patterns indicate that Republicans anticipate retaining these seats. Democratic advertisers account for less than 1% of the $25.5 million spent on advertising during Indiana’s 2026 primary contest, according to available data.
In 2026, half of Indiana’s 50 state Senate seats and all 100 state House seats will be up for election.
Comparisons to Other States
In contrast to Indiana, lawmakers in Alabama, Tennessee, Louisiana, and other states have passed redistricting measures designed to enhance Republican control. Representatives in Alabama and Tennessee have already called special sessions to discuss redistricting following a landmark decision last week that facilitated revisions in Louisiana.
Democrats recently redrew voting maps in some regions.
Trump’s Final Push Before the Vote
In the days leading up to Indiana’s contentious primary, Trump urged his followers on Truth Social to vote for a “true Maga Warrior.” He also provided a link to polling locations through his party’s campaign platform, “Swamp the Vote,” to assist voters.
