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.

Is the GOP lagging on nominating women?

Over on Bluesky, Boston magazine contributing editor David Bernstein shared that the GOP has nominated men in all 10 open-seat solid-Republican districts going into tonight. A similar outcome for Democrats would be shocking, given that a vast majority of Democrats say that there are too few women in politics. But the GOP doesn’t share the same sentiment.

In 2020, we watched where Republicans were nominating women and found that, through August 2020, only 6 out of the 77 Republican women who had won their primaries did so in a safe Republican seat. A whopping 49 of those women won in safe Democratic seats.

In other words, the GOP women won primaries in places where they wouldn’t win in November. We’ll have more to say about that this year, after a few more primaries have passed.
