Six signals to watch as midterm election results come in

With control of Congress at stake Tuesday, midterm election night can be hard to read, with races for governor, Senate, House and state legislatures all reporting at once. Here are six signals that could reveal early which party comes out ahead.

The first clues arrive early. Indiana and Kentucky report in the 6 p.m. Eastern hour, and Florida, mostly on Eastern time, delivers a wave of House results in the 7 p.m. hour. Indiana's 5th Congressional District and Kentucky's 6th are Republican-held seats now more competitive than expected; if either is close or tipping Democratic, it could signal soft Republican turnout and a bigger wave. Florida's 22nd District is held by a Democrat but was redrawn to favor Republicans, and the heavily Latino 27th, which President Trump won by double digits, could show how Latinos are voting.

Second, watch whether Republicans reach 46% among independents, a crucial swing group that turns out less in midterms. Mitt Romney won 55% of independents in 2012 yet still lost the presidency. After a decade of realignment, with blue-collar white voters moving toward Trump and better-educated white voters shifting Democratic, Republicans have done well when they hit at least 46% of independents and lost when they fall short.

Third, watch Black turnout in Michigan's Senate race, central to control of the chamber. A Republican flip would raise the number of Republican-held seats Democrats must win from four to five. For Democrat Abdul El-Sayed, the key is Black voters in Wayne County: running up the score in and around Detroit gives him a path to victory, while falling short there, a known vulnerability, makes it much harder. In the Trump era, Democrats have needed at least 68% in Wayne County to carry Michigan, unless they overperform in the suburbs, as Sen. Elissa Slotkin did in winning with 63% in 2024.

Fourth is the margin among young voters. Since 1992, 43% of registered voters ages 18 to 29 have cast ballots in presidential years, but that drops to 21%, just one in five, in midterms. Over the past two decades, Democrats have thrived when they won this group by more than 20 points. The exception was 2022, when a 28-point edge helped limit losses to nine House seats while gaining a Senate seat. In 2024, an 11-point margin coincided with Trump's victory.

Fifth, in Texas, watch the gap between Gov. Greg Abbott and Ken Paxton. Past Texas polling errors that underestimated Republicans feed skepticism that Democrat James Talarico's margin-of-error lead in polling averages is enough. No Democrat has won statewide in Texas since 1994 or won a Senate race there in 38 years, and Trump carried the state by 14 points in 2024. In 2018, Ted Cruz drew about 400,000 fewer votes than Abbott yet still won by more than 200,000. If Paxton trails Abbott by more than 400,000 votes, Talarico may have an opening.

The rest of Talarico's path runs through South Texas. Beto O'Rourke won 64% of Latino voters in 2018, when they made up 26% of the electorate, exit polls showed. He would need to top both marks and improve on O'Rourke's totals in heavily Latino counties such as Cameron, Hidalgo, Webb and Nueces. Also watch the fast-growing Dallas suburbs of Collin, Denton and Tarrant.

Finally, watch party identification in the exit polls. Self-identified Democrats fell to a low of 31% in 2024, as the party's base has grown more liberal and more disaffected with its leadership. Democrats were among the most enthusiastic groups in the latest NPR poll, but they likely need to exceed 31% of the electorate to do well. Opposition to Trump could unify the left: 53% of likely voters strongly disapprove of his job performance. Races like the Michigan Senate contest and Michigan's 7th Congressional District, where progressive Democrats are running in purple territory, will test that unity and preview the party's ideological future before the 2028 presidential primary.
