Primary results show Trump’s power over Republican Party remains strong

U.S. President Donald Trump wanted political retribution against Republican incumbents in Indiana who defied his calls to help the GOP in Congress by redrawing election boundaries.

On Tuesday night, Trump largely got his revenge. 

Republican voters in ruby-red Indiana picked Trump-backed candidates in six of eight contested party primaries for the state Senate, knocking out the incumbents who stood up to the president, according to projections Tuesday evening by U.S. media outlets.

Despite polls suggesting his popularity is dwindling among the broader U.S. population, the results in Indiana indicate Trump’s influence on the Republican base remains strong.

Laura Merrifield Wilson, a political science professor at the University of Indianapolis, says it’s highly unusual for Indiana’s state-level incumbents to be defeated in a primary.

“That is a testament to President Trump’s popularity in our state, particularly of course amongst Republican primary voters,” Wilson told CBC News.

Trump has held unrivaled sway over the Republican Party for the past decade, with the power to make or break a GOP politician’s career through one social media post.

In a post on Tuesday while the Indiana primary polls were still open, Trump praised the candidates he’d endorsed as “Great Patriots” and slammed their Republican incumbent rivals as “people who couldn’t care less about our Country.”

TV ads targeted incumbents who defied Trump

Trump’s disdain for the Indiana incumbents was sparked by their refusal to go along with his push to redraw election maps in ways that would likely put more Republicans into the House of Representatives in the midterms this fall and give the GOP a better chance to keep control of Congress. 

The Republicans who defied Trump faced a primary onslaught that included not only the president’s forceful endorsements of their rivals, but also deep-pocketed ad campaigns and on-the-ground organizing by Turning Point USA, the pro-Trump activist group founded by the late Charlie Kirk. 

Groups spent nearly $12 million US on TV ads for Indiana’s Senate primaries, roughly 24 times the amount spent in the last primary campaign, most of it attack ads against the incumbents, NBC news reported on Monday.

The end result: five of the seven incumbents targeted by Trump and his allies lost in Tuesday’s primaries, and a sixth was leading a tight race by a margin of fewer than 200 votes with five per cent of ballots still to be counted.

Wilson said the unusually high ad spending was clearly a factor in the defeat of the incumbents, and Trump’s endorsement “was certainly a benefit” to their challengers.

Trump began his gerrymandering effort in red states last year. Election boundaries in the U.S. are controlled by states and are traditionally only changed once a decade, in the year after the census, which last took place in 2020.

Republican state legislators in Texas quickly embraced Trump’s call for redistricting, changing boundaries in a way that voting patterns suggest could flip as many as five House seats to the Republicans in the midterm elections this fall.

However in Indiana, several Republican state senators refused to comply with Trump’s plan for redrawing the election map of the Hoosier state, despite heavy pressure from the White House, and even some bomb threats against them.

Their defiance triggered Trump to slag the senators as “RINOs” (Republican in Name Only) who “should be ashamed of themselves.”

While some political observers suggested Trump’s tactics might backfire with Indiana Republican voters who believe strongly in the principle of states’ rights, Tuesday’s results put such speculation to rest.

“Big night for MAGA in Indiana,” declared Republican U.S. Sen. Jim Banks in a post on X, usng the acronym for Trump’s Make America Great Again movement. “Proud to have helped elect more conservative Republicans to the Indiana State Senate.”

Trump won Indiana by comfortable margins in all three of the presidential elections he has contested.
