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.

In Ohio's 13th District, former state Sen. Kevin Coughlin is projected to win, according to ABC News. With 27 percent of the expected vote reporting, Coughlin is way out ahead with 67 percent of the vote, putting him well ahead of Hudson City Councilor Chris Banweg, who has 26 percent. Coughlin had a slight fundraising edge over Banweg, but it wasn't evident coming into the election if one candidate had a clear upper hand. Turns out, Coughlin did. Now he'll face Democratic Rep. Emilia Sykes in the purple seat that sits around Akron, south of Cleveland, one that Biden would have only carried by 3 percentage points in 2020.

I've been keeping a close eye on Trump's Truth Social account, and one thing I noticed this time around is that his endorsement of Merrin in Ohio's 9th came fairly late in the game. He endorsed Moreno on December 19, but he didn't issue an endorsement in the 9th until yesterday afternoon!

Now, there may be reasons Trump waited to make an endorsement in the race. A key Trump ally in the state, Rep. Jim Jordan, had already endorsed Riedel, so maybe Trump was trying not to get on his bad side. But the fact that he waited so long will almost certainly diminish the impact of the endorsement with voters.

When it comes to the Senate race, Tia, the fact that it's as close as it appears to be even given Trump's endorsement may already tell us something about his impact in these sorts of races. The non-MAGA establishment obviously still holds significant sway among voters, at least in Ohio.

All that is a long-winded way of saying that I'm not sure Trump is showing much strength with his Ohio endorsements. The races are very close, so whatever he's doing hasn't seemed to impact the electorate as much as he would probably hope to.
