If you've been paying attention to Indiana politics lately, you know today is bigger than a typical primary. There's a lot on the ballot- from county sheriff races you can feel in your own backyard to a national political showdown that's drawing eyes from Washington all the way to your polling place.

Let's break it down.

The big story: Trump vs. his own party

The headline story in today's Indiana primary isn't a Democrat vs. Republican fight. It's Republicans vs. Republicans and it starts with a vote that happened last December.

Last December, a majority of Republicans in the Indiana State Senate voted down a congressional redistricting attempt that President Trump had pushed hard- it would have overhauled two Democratic-held districts to bolster the GOP's chances of keeping control of the U.S. House in this fall's midterm elections.

Trump did not take it quietly. He posted on Truth Social that "every one of these people should be primaried". That threat became reality.

Of the 21 Republican senators who voted against redistricting, eight are running for reelection this year. Trump has endorsed primary challengers against seven of them, and his allies have spent millions of dollars on races that rarely get much attention from Washington, according to reporting by the Associated Press.

The senators who voted no say they were listening to their constituents- not Washington.

Tonight's results will tell us a lot about whether Trump's grip on his own party is holding- or starting to slip.
