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.

2023 elections to watch: Virginia legislature

—Nathaniel Rakich, 538

In Virginia, Republican Gov. Glenn Youngkin and the GOP-controlled House of Delegates have been at loggerheads with the Democratic-controlled state Senate since the 2021 election. But today, all 100 House seats and all 40 Senate seats are on the ballot, giving Republicans a chance of capturing a “trifecta” — control of the governorship and the entire General Assembly. Such a result would have major ramifications, most notably for abortion rights. Youngkin has pushed for a 15-week abortion ban, which would reverse Virginia’s status as the last Southern state with lesser restrictions on abortion rights.

There hasn’t been much polling, but things look highly competitive. A handful of polls in late September through late October asked likely voters if they planned to vote for a Democrat or Republican in the upcoming election and found party preferences pretty evenly split.

Control of both chambers will come down to a small number of hotly-contested districts, which look much different after the latest round of redistricting. The most competitive seats lie in suburban or exurban areas of the state’s three major metropolitan areas of Northern Virginia, Richmond and Hampton Roads. In the Senate, Democrats may have a slight edge, as they appear favored in 19 seats to the GOP’s 16. That means Republicans would need to win four of the remaining five highly competitive seats to get to a 20-20 tie (which would hand them control via Republican Lt. Gov. Winsome Sears’s tiebreaking vote). The House map looks closer to a pure toss-up, with fewer than 10 seats likely to decide things.

Welcome to election night 2023! Polls are open today in at least 37 states, and Americans have been casting their votes on everything from governorships to local referenda. 538 analysts will be here throughout the evening to bring you live updates and analysis from races across the country.

We’ll be closely tracking returns in some of today’s biggest races, including governor’s races in Kentucky and Mississippi; state-legislative contests in Virginia, New Jersey and Mississippi; Ohio’s ballot question on whether to codify the right to abortion; a Supreme Court contest in Pennsylvania; and a handful of congressional and state-legislative special elections.

We’ll also be keeping an eye on down-ballot and local contests, like mayoral and school board elections, and we’ll be digging deeper on what these results mean — or don’t mean — for Democrats, Republicans and, of course, the 2024 election. In addition to battling over who will control state and local policy, parties and activists are testing the waters for even bigger organizing and messaging efforts heading into next year. Will abortion continue to drive Democratic turnout and enthusiasm over a year after the Dobbs decision? How will races play out in states with newly drawn maps? Will Republicans sweep all three governor’s races this fall? Will Democrats continue to overperform in special elections?

There are more than 275 mayoral races on the ballot around the country today, ranging from the Jersey Shore’s Point Pleasant Beach (population 4,828) to big cities like Houston and Philadelphia. I’ll be closely tracking the results in those two cities, but will also keep an eye throughout the night on local news for surprising outcomes in lower-profile races.

Former Philadelphia City Council member Cherelle Parker is highly favored to replace Mayor Jim Kenney, who is term-limited, after winning an expensive Democratic primary in May. Another former City Council member, David Oh, won the Republican nomination uncontested. A Republican victory would be a shocker here — we don’t have any public polling of the general election, but about three in four Philadelphia voters are registered Democrats, and the city hasn’t had a Republican mayor since 1952. However, Oh has won over Democratic voters before, so it’s a race worth watching. Parker too is a moderate within her party, and made news when she beat out progressive primary opponents with a tough-on-crime platform including support for controversial stop-and-frisk policing tactics. Both candidates would make history with a win: Oh would be the first Asian American ever to serve as mayor of Philadelphia, and remarkably, Philadelphia has never elected a female mayor, so Parker is likely to be the first.

In Houston, the mayor’s race is more competitive, but tonight is likely just the first half of a two-part series. If no candidate receives 50 percent of the vote, the top two performers progress to a runoff election, which will be held on Dec. 9. And with 18 names on the ballot today, it’s going to be tough for any individual candidate to coalesce half of the vote. This race is technically a nonpartisan election, but the top two candidates are longtime Democratic state Sen. John Whitmire and longtime Democratic U.S. Rep. Sheila Jackson Lee. Whitmire is by far the top spender in the field. The only public poll we’ve seen so far — conducted by the University of Houston Sept. 30-Oct. 6 — also found Whitmire leading the race with 34 percent of likely voters, followed by Lee at 31 percent. Although they’re both Democrats, Whitmire, who has framed his candidacy around working across the political spectrum, received more support from Republicans and independents in the University of Houston poll. Lee received more votes from Democrats, women and Black voters. In a hypothetical head-to-head matchup, Whitmire led 50 percent to 36 percent.
