Indiana primaries 2024: Spartz survives, big spenders prevail

538 tracked several establishment-versus-insurgent GOP primaries.

Tuesday saw the resolution of several major Republican primaries in Indiana: Voters selected the men who will likely become the state’s next U.S. senator and governor, and three open U.S. House seats were the canvas for fierce primary battles between the establishment and populist wings of the GOP. A maverick Republican incumbent also successfully defended her seat after waffling over her decision to seek reelection.

Braun is very conservative on abortion

Braun's record in the Senate on abortion has earned him an A+ rating from the anti-abortion Susan B. Anthony Pro-Life America. He's introduced several anti-abortion bills, including a parental notification bill last year that would require parents to be notified when their minor child seeks an abortion and give them a chance to stop it. Before the ruling that overturned Roe v. Wade, Braun had suggested that interracial marriage and same-sex marriage, both issues also related to rights to privacy, should be left to the states, before walking that back and saying he'd misunderstood the reporter's question. Still, he has praised Indiana's near-total abortion ban, but he's also said more recently that he expects tweaks in the coming years.

Of course, Braun was only one of many anti-abortion candidates I'm watching tonight. Messmer's projected win in the 8th District (according to reporting by ABC News) adds another anti-abortion victory to the list, and ABC News is now reporting that Baird is projected to win in the 4th District.
