TAMPA, Fla. (WFLA) — Democrats or Republicans could walk away Tuesday with the majority in the U.S. House of Representatives, according to NewsNation/Decision Desk HQ.

You can follow along with the results as they come in on the live map below.

With control of Congress at stake, the ever-tight contests for the House and Senate will determine which party holds the majority and the power to boost or block a president’s agenda, or if the White House confronts a divided Capitol Hill.

In the end, just a handful of seats, or as little as one, could tip the balance in either chamber. With a 50-50 Senate, the party in the White House determines the majority, since the vice president is a tie-breaker.
