We won't be tracking the GOP primary for Indiana Senate tonight, and that's because Republicans have effectively cleared the field for Rep. Jim Banks, who is running unopposed for Sen. Mike Braun's seat (which Braun is leaving to run for governor).

Banks is a MAGA stalwart who has the endorsements of former President Donald Trump, the state Republican Party, and the National Republican Senatorial Committee. He supports a nationwide abortion ban after fetal cardiac activity is detected and sent a memo to his House colleagues in 2021 urging Republicans to "lean into the culture war" in the party's push against critical race theory. He has represented Indiana's 3rd Congressional District since he was first elected in 2016.

By consolidating around Banks early, the Republican Party avoided what could have been a messy primary fight. Former Gov. Mitch Daniels, who'd left politics to head Purdue University, had considered jumping in, saying he would "soften the harshness and personal vitriol that has infected our public square." Trump had called him a "weak RINO," while Mark Lubbers, a Daniels advisor, referred to the former president and his family as the "Trump crime family" in response. Such a primary fight might have thrown the state party into chaos, as seen in Arizona, Georgia and Michigan, as Trumpworld continues to wrest control of the party from more establishment Republicans.

Two Democrats are running for the chance to take on Banks, but either would face an uphill battle. Indiana hasn't had a Democratic senator since Braun ousted Democratic Sen. Joe Donnelly in 2018, and the Republican candidate in 2022, Sen. Todd Young, defeated his Democratic opponent by 21 percentage points.

Happy primary day, Hoosiers! Indiana is easily forgotten on the primary calendar, sandwiched as it is between sexier states like Pennsylvania and Maryland (don't look at me like that — have you seen that flag?). But if you care about how well Congress functions, you'll want to pay attention to today's primaries, even if you don't watch "Stranger Things" and "Parks and Rec" on repeat.

As my colleagues recently so beautifully illustrated, there are several parties within the parties in Congress. On the Republican side, there are pragmatists who fall in line with party leadership — and then there are obstructionists who tend to make life harder for them.

This year, there are three open House seats in Indiana that could send either type of representative to Congress. And because these seats are safely Republican, today's contests, not November's, will effectively determine that. Elsewhere in the state, Rep. Victoria Spartz — the Hamlet from Hamilton County — could be the second incumbent representative of the cycle to lose reelection, and GOP primary voters will also choose who will likely become the next chief executive of this state of nearly 7 million people. So yeah, the stakes are high!

We won't have to wait long to find out the winners: Polls close in most of Indiana (the parts in the Eastern time zone) at 6 p.m. Eastern, with the parts of the state in the Central time zone following suit at 7 p.m. Eastern. Follow along with us for the next few hours, won't you?
