Americans vote in the midterm elections on Tuesday, with control of Congress on the line, Fox News and PBS News report.

Republicans hold the Senate 53-47 and a very thin House majority. The party in power has usually lost seats in midterm years, Fox News notes. Its final Power Rankings rate the Senate a toss-up and point to Democrats winning the House.

Voters in 36 states will also pick governors. All but four states are holding elections for their legislatures, Fox News reports.

There are 145 statewide ballot measures in 39 states, PBS News and NBC News reported in guides on October 26. California and Colorado have the most, with 14 each.

Eleven states will vote on voter ID rules or on language saying only citizens can vote, according to the two outlets. Noncitizens already cannot vote in federal or statewide elections, PBS News notes.

Abortion is on the ballot in four states. Idaho, Nevada and Virginia will vote on measures to allow or protect access. Missouri will vote on repealing an abortion-rights amendment it passed in 2024.

Californians will decide on a one-time 5% tax on billionaires' wealth. Washington state voters will decide whether to repeal a new 9.9% tax on income over $1 million a year. Several states will also vote on transgender students in sports.

The first polls close at 6 in the evening Eastern time, and the last ones, in Alaska, close at 1 in the morning Eastern time, Fox News reports.

What we know: Congress, 36 governorships and 145 measures are on the ballot.
What we don't: Which party will control each chamber.
