Voters turned out Tuesday to vote for the next President of the United States, a race between Republican Donald Trump and Democrat Kamala Harris. Democrats and Republicans are also battling for control of the U.S. Senate this election. There are 34 Senate seats up for grabs, with about a half dozen of those likely to be decided by tight margins .

Sen. Sherrod Brown (D-Ohio) and Republican Bernie Moreno will face Tuesday in the Ohio Senate race. A win in Ohio would expand Republicans’ majority, and the race has become the most expensive contest on the Senate map this year.

Democrats hold a slim majority with 51 seats, including four independents who caucus with them, while Republicans hold 49 seats. This year's election is set to shape the legislative landscape for years to come, with both parties fighting for every possible seat.
