In Illinois' 12th District, Bost is ahead of challenger Bailey by 10 percentage points, 55 to 45 percent, with 36 percent of the expected vote in. But there's still a lot of vote to be counted in the eastern part of the district, where Bailey is stronger.

In Cuyahoga County, Ohio, home to Cleveland, incumbent Prosecutor Michael O'Malley is fending off a strong challenger from the left, former public defender Matthew Ahn. O'Malley has been criticized for a string of wrongful convictions and death sentences, but currently leads Ahn 64 to 36 percent, with 20 percent of ballot scanners in the county reporting, according to the Cuyahoga County Board of Elections.

For those of you who aren't familiar with Derek Myers, the 31-year-old who accidentally sent out a concession statement several hours before polls closed, you're in for a real treat. The Cincinnati Enquirer recently wrote a pretty comprehensive expose into his past legal troubles, which is definitely worth reading (especially given that Myers has filed a libel suit against the paper).

Also worth reading is Myers' response to the reporters who wrote the article, which the Enquirer published in full and which included such gems as when Myers says he once told a deputy who pulled him over for speeding that he "was not trained enough to handle someone of Derek's caliber," and later tells the reporter, "you are playing in dangerous waters, my little friend."

If that's not enough for you, Myers previously made news last year for his brief stint working for embattled New York Rep. George Santos, who he accused of sexual harassment.

In Ohio's 15th District, Zerqa Abid, an anti-violence and anti-gang advocate in the Columbus area, is projected to lose her primary against former state Rep. Adam Miller, according to ABC News. Miller will face Republican incumbent Mike Carey in the fall. The district is fairly safely Republican, and Carey received Trump's endorsement when he first ran in an open special primary in 2021.

In all, 13 of the 17 Democratic women running tonight are projected to win their primaries, including nine incumbents.

Only three of the eight Republican women we were tracking won their primary races: Two of them were uncontested and are in deep blue districts, where they are unlikely to win in November. One, Miller in Illinois's 15th, is the incumbent. On the flip side, 13 of the 17 Democratic women we were tracking won their races, many of them incumbents likely to hold their seats in November.

Women have record representation in Congress now, but of course still lack parity. But in this election, issues that women care about, namely abortion and reproductive rights, are poised to make a difference. Democratic voters could be motivated to turn out to protect abortion rights at the national level, and Democratic candidates are likely to run on the issue going forward.
