Jim Banks

When Indiana Senate Republicans struck down a proposal to redraw the state's congressional map mid-decade, President Donald Trump enlisted U.S. Sen. Jim Banks to spearhead his retribution effort.

What followed was what one expert deemed "the political operation of a lifetime": a relentless, multimillion-dollar campaign that wiped out more GOP state senators in a day than had been unseated since 2002.

Banks, 46, was not the only Indiana Republican who endorsed and propped up the victorious candidates. And, in an interview with IndyStar in June, Banks himself credited the success to the power of Trump's endorsement.

"It shows the lesson that we've learned over and over again," Banks said. "First of all, that there's no more powerful endorsement in politics today, maybe ever, than President Trump's endorsement."

But, as political scientists and GOP insiders who spoke to IndyStar pointed out, Banks' influence and aggressive presence in the GOP as just a freshman U.S. senator is striking. It comes at a time of flux for the party in Indiana: the state is solid-red, voting for Democrats for president only five times since the turn of the 20th century, but was the sole state to reject Trump's call to redistrict at the time.

Amid the indecision, Banks has emerged as a major contender for the party's de facto leader. While there are other powerful Indiana Republicans driving policy change, most haven't been as outspoken politically.

"It is very clear that Jim Banks is the undisputed leader of our party," Kory Wood, a partner at the Republican campaign consulting firm Ascent Strategic, said.

It's not the only election Banks has had a hand in. He's attacked state Sen. Liz Brown, R-Fort Wayne, even after she received a Trump endorsement, in her primary race against Banks staffer Darren Vogt. He also played a central role in flipping the GOP nomination for secretary of state upside down after he said he said became convinced the incumbent, Diego Morales, couldn't win, backing Max Engling's last-minute entry to the race instead.

One-by-one, other powerful Republican insiders followed Banks' lead.

Whether Engling is able to nab the GOP nomination at the party's convention June 20 will be the next test of Banks' influence.

Is Banks the future of the party?

Indiana has been somewhat of an unlikely breeding ground for powerful Republican politicians.

Former Indiana Gov. Mitch Daniels once entertained a run for president. The state has also produced an unusual amount of vice presidents, including former Vice President Mike Pence, and powerhouse U.S. senators like the late Richard Lugar.

But now that many of the party's previous leaders have stepped aside to write books or lead universities, they've left a void for more recent Hoosier politicians to fill.

Banks has made it clear he wants to be a contender, and he has powerful allies in his corner. Vice President JD Vance, in an unsolicited statement to IndyStar, called the senator a "key ally" with a "game-changing" impact.

Political science experts and party insiders who spoke to IndyStar agreed Banks is the most prominent political voice in the Indiana GOP, describing him as imposing, thoughtful and politically savvy. His political opponents have given him extra attention, too, calling him "dangerous" and "divisive."

But the very qualities that make Banks a target for Democrats are seemingly part of his appeal. He's championed a more aggressive version of the GOP, a contrast to what Banks has deemed "squishy and soft Republicans" who won't do what it takes to win.

"It's a duty that I have to be a leader in our party, especially for our state and also in our country," Banks said. "And I take that role very seriously."

Banks can also point to humble origins: the son of a factory worker and nursing home cook, Banks grew up in Columbia City, Indiana, a small town that claims it was once the largest producer of blue jeans in the world. In the decades since, he has ascended from Whitley County councilor, to state senator, to U.S. representative, to U.S. senator.

In the U.S. House of Representatives, Banks chaired the Republican Study Committee, a powerful conservative caucus, and narrowly lost a bid for majority whip. When he ran to be a senator, he went unchallenged in the primary, seemingly warding off any protest from the more moderate wing of the party, including from Daniels. It was likely part of his strategy, Laura Merrifield Wilson, a political science professor at the University of Indianapolis, said.

"It seems that is a Jim Banks playbook that has worked very effectively," she said.

In the U.S. Senate, Banks has so far sponsored more legislation than any other freshman senator, according to the legislation tracker Quorum, nearly a fifth of which was bipartisan. He's also boasted his ability to leverage his relationship with the White House to secure federal investment in Indiana, such as a Department of Energy loan for Wabash Valley Resources' fertilizer plant and carbon sequestration project, making Indianapolis a U.S. Department of Agriculture and Supplemental Nutrition Assistance Program hub and securing a one-star reserve flag officer at Naval Weapons System Crane.

Banks' intensity has even led some observers to speculate whether Banks could one day run for governor or beyond. Though he didn't entirely rule it out, the senator told IndyStar that his current ambition is chairing the Senate Armed Services Committee.

A shifting political landscape

Though Banks has had a hand in Indiana politics for years, the contentious state senate primaries provided an opportunity for the U.S. senator.

The state party wasn't in agreement on what to do, said Michael O'Brien, who served as former Gov. Eric Holcomb's 2016 campaign manager, teeing up Banks for a "boots on the ground" campaign against the incumbent senators.

But Banks' willingness to make bold moves are aided by the political climate, where aligning with Trump's objectives seems to be working, at least so far.

"Todd Young and Mike Pence are sort of the GOP of yesterday," Purdue political science lecturer Martin Sweet said. "Trump and Banks are more the GOP of today."

But some political observers also ranked Young high for his influence in the party. The senator has taken a far less public role in shaping the party's direction but was described by some party insiders as a team player who wields strong relationships with local elected officials, fundraises well and has delivered notable legislation like the CHIPS and Science Act, which has attracted billions of dollars in investment in Indiana, and the state's designation as one of two drone test sites. As recently as 2022, he faced little formal political pushback. His only primary opponent was kicked off the ballot after failing to gather enough signatures.

In response to an IndyStar question May 7 about the results of the state senate races, Young said he tended to stay out of the business of the Indiana General Assembly and instead hoped to "unify the Indiana Republican Party around a positive vision."

He also hasn't weighed in on the secretary of state race.

“The guy never gets rattled," former Republican state legislator Mike Murphy said of Young. "Never picks a fight."

And while other GOP leaders, including those more ideologically similar to Banks, have wielded influence over the party, political science experts told IndyStar that none have risen to the level of Banks.

“(Gov. Mike Braun) just has no juice," Sweet said. "He’s not driving anything."

In response to a request for comment on Banks' role in the party and sentiments that Braun is not driving the political conversation in Indiana, Chief of Staff Josh Kelley said in a statement that “Governor Braun and Senator Banks are working collaboratively with President Trump to address affordability and improve the quality of life for Hoosiers across the board.”

Braun was an early proponent of redistricting but appeared less vocal ahead of the primary elections, releasing a batch of endorsements shortly before the election and pledging funds that paled in comparison to the spending by Banks-linked groups.

One Republican operative compared it to a football game: while Banks was running up the score, he said, Braun came in during the final two minutes of the game.

Braun has also opted to stay out of the convention drama by not endorsing any of the candidates vying to be the GOP secretary of state nominee. The governor is, of course, in more awkward of a spot than Banks, as he'll have to work with whoever wins the November general election. Plus, political conventions can be unpredictable.

While several party insiders agreed that Banks has built an impressive political apparatus, it's difficult to divorce his impact from that of President Trump's.

"I think his operation is a well-connected and congruent relationship with the White House in terms of goals," Sweet said. "I just don't see this as a massive independent play."

The convention question

Banks' command over the party could hinge on the outcome of the Republican convention June 20.

The senator's decision to throw his support behind Engling was somewhat of a gamble. If delegates choose Morales, it could be perceived as a blow to Banks. The inverse is also true, experts and insiders told IndyStar.

"If [Engling] wins this, [Banks] will be the guy controlling the party," one Republican operative said.

So far, the reversal appears to be successful. Engling had Banks' backing shortly before he entered the race and quickly earned the support of other prominent Republicans. Whether delegates fall in line is a different question entirely, as they've earned a reputation for bucking expectations after upsets in 2024 and with Morales himself in 2022.

It's a crucial juncture for the GOP. Whoever comes out of the convention as the nominee will face Democrat Beau Bayh, who has proven he has the ability to fundraise and stick to an anti-corruption message.

"I do think there is a powerful feeling among Republicans of 'Can we stop Beau Bayh before he gets started?'" Sweet said.

Stopping Bayh, and stymying a Democratic Party comeback in the process, would likely further cement Banks as a major player in the party. Only time will tell if the gambit pays off.
