In Kentucky, 60 percent of the expected vote has reported in the governor's race, and Beshear leads by 5 points over Cameron, 52.5 percent to 47.5 percent. But there's more good news for Beshear: He's mostly running ahead of his 2019 numbers in the counties where most of the vote has come in. At this point, 37 counties have reported at least 90 percent of their expected vote (out of 120 in the state), and across them Beshear is running 4.7 points ahead of his 2019 margin. Now, most of those counties are small — together, they made up about 23 percent of the statewide vote four years ago. But those counties also don't include the two biggest Democratic bases of support in Jefferson and Fayette counties (Louisville and Lexington).

As our colleague Amelia Thomson-DeVeaux has written, the Dobbs v. Jackson Women's Health Organization Supreme Court decision last year has turned reproductive health and abortion rights into a liability for Republicans at the ballot box. After Republican-led states began restricting abortion rights in the wake of the decision, voters around the country have supported increasing abortion rights when it was directly on the ballot and helped Democrats over-perform in the 2022 midterms. Support for abortion has been rising. A win for the "yes" in Ohio tonight could mean abortion rights will stay on voters minds as we head into the 2024 election season.

Democrats face test in Kentucky governor's race:

The clock has chimed for 8 p.m. Eastern, which means polls have closed in four more states voting today. In Mississippi, the main action is the state's governor race, although there are also down-ballot races for statewide and legislative office. In New Jersey, the state legislative elections are the main focus. In Pennsylvania, there's a contest for the state supreme court that could be important for how the court decides election law questions in the 2024 election (among other things). And in Rhode Island, there's the special election for the vacant 1st Congressional District left behind by former Democratic Rep. David Cicilline.

Since the Supreme Court overturned Roe v. Wade in June 2022, abortion rights issues have won every time they’ve been on the ballot. Tonight, we’ll see if that trend holds as Ohio voters will decide whether to enshrine abortion rights in their state constitution.

But more broadly, abortion rights proved to be a motivator for Democratic voters in last year’s midterm elections, helping propel their party to better-than-expected midterm election results. Abortion remains an important issue for Democrats: 86 percent view it as very or somewhat important in the Oct. 25 weekly YouGov/The Economist poll. It’s a sharp contrast to Republicans, who are much less likely to support abortion rights than the general electorate, and also less likely to rank it as an important issue: only 68 percent did so in the YouGov/Economist poll.

That could keep Democrats likely to show up at the polls even when abortion is only implicitly on the ballot, like in Virginia, where Republicans have a chance to win full control of the state government. Hoping to drive turnout, Virginia Democrats have campaigned on abortion rights in competitive legislative districts this year, warning voters that Virginia could join other Southern, Republican-led states in banning abortion. Republicans in the state have denounced these efforts as fearmongering.

If the Ohio abortion-rights amendment wins and Democrats once again outperform expectations in other elections, it could be a sign that abortion is still driving Democrats to the polls. But no matter what happens tonight, abortion will likely continue to shape the presidential primary and election season that begins next year.
