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.

Polls are closed in the eastern half of Kentucky and very early results are starting to trickle in. Be aware of a possible blue mirage and a possible red shift later: the early votes, which tend to favor Democrats, are counted first.

Key election races across US with implications for 2024:

They’re not the sexiest things on the ballot, but one congressional and seven state-legislative special elections are also taking place today. The highest-profile one is the special election between Democrat Gabe Amo and Republican Gerry Leonard Jr. to fill former Rep. David Cicilline’s seat in the U.S. House. There isn’t much suspense about who will win, though: That seat — Rhode Island’s 1st District — is safely Democratic. As a result, Amo, who is Black, will almost certainly become the first person of color to represent Rhode Island in Congress.

However, it’ll still be worth paying attention to the final margin in that race and the other special elections. As we’ve written in the past, when one party consistently outperforms its usual margins in special elections, it has historically boded well for the party in the subsequent general election. And so far in 2023, Democrats have been winning special elections by significantly more than the partisan baselines of those districts would predict. I’ll be watching to see if that pattern continues tonight.

Three Southern states hold gubernatorial elections the year before a presidential election: Kentucky, Louisiana and Mississippi. But despite the strong Republican lean of these states, Democrats held the governorships of Kentucky and Louisiana coming into this election. The GOP began the year with a real shot of winning all three, and entering today, they’re already one step of the way there: On Oct. 14, Republican state Attorney General Jeff Landry won Louisiana’s governorship outright, avoiding a November runoff. This was an open-seat pickup for Republicans since Democratic incumbent Gov. John Bel Edwards was term-limited. Now, all eyes are on Kentucky and Mississippi, where each incumbent governor is slightly favored to win reelection in a competitive contest, based on limited polling and race ratings from Inside Elections, Sabato’s Crystal Ball and The Cook Political Report.

In Kentucky, Democratic Gov. Andy Beshear faces Republican state Attorney General Daniel Cameron. Beshear won in 2019 by less than 1 percentage point against an unpopular GOP governor, but has maintained a high approval rating despite his party identification. He’s painted Cameron as an extreme Republican because of Cameron’s support for Kentucky’s near-total ban on abortion. That message might work: Although Kentucky is conservative, voters last year rejected a constitutional amendment that would have formally stated there is no right to abortion under the state constitution. In his campaign, Cameron has tried to tie Beshear to the unpopular Biden while criticizing the incumbent for his vetoes (later overridden) of anti-transgender legislation. We have very little polling here, but in mid-October competing partisan polls from Hart Research and from co/efficient each found Beshear ahead by differing margins. However, a poll from Emerson College released on Friday showed the two candidates running just about even.

On the flipside, Mississippi is more likely to remain in Republican hands. Republican Gov. Tate Reeves faces Democratic Public Service Commissioner Brandon Presley, one of just two Democrats in Mississippi’s executive branch (and, yes, a second cousin of Elvis). Reeves has played to the GOP base by highlighting his opposition to transgender women playing women’s sports, while Presley has tried to ding Reeves by connecting him to an ongoing scandal involving the misuse of federal welfare funds by the Mississippi Department of Human Services. We have even less polling to go on here than in Kentucky, however. A late October Public Policy Polling survey on behalf of the Democratic Governors Association gave Reeves only a tiny edge, but that’s maybe the rosiest picture for Presley. The next most recent poll from the Mason-Dixon/Magnolia Tribune put Reeves up 8 points.
