How many House seats are still undecided? GOP close to majority

As of Monday morning, 19 House races were still uncalled, with Republicans only needing four more seats to keep the majority.

As of 7:30 a.m. ET, Democrats had 203 seats to Republicans' 214. A party needs 218 seats for a majority.

If Republicans keep the House majority, that would give the GOP control of all three branches of government. Senate control has already been decided - flipping away from the Democrats - and a presidential victory has been called for Donald Trump .

Many undeclared seats for the House on Monday were in western U.S. or in swing districts.

Here is a brief look at what seats have already flipped, and what's left to be called:

Which House seats flipped?

So far, Republicans have flipped and picked up three seats, according to race calls made by The Associated Press. All were from key battleground states.

The flips were Tom Barrett in Michigan's 7th District, and Ryan Mackenzie and Robert Bresnahan in Pennsylvania's 7th and 8th Districts, respectively.

Which House seats are still undecided?

As of Monday morning, 19 races for House seats were still left to be called.

The majority of those races are in California, with others in Alaska, Washington, Oregon, Colorado, Louisiana, Iowa, Ohio, Maine and two in Arizona.

Republicans only need four more seats to win a majority, and were leading Monday in 9 of the races that remain to be called.

Here are the races in question:

California, 10 seats

House seats for 10 races in California are yet to be called: districts 9, 13, 21, 22, 27, 39, 41, 45, 47 and 49.

Republicans are leading in four of those races (Districts 13, 22, 41 and 45), with Democrats leading in the remaining six.

One lead is notable for Democratic candidate George Whitesides in District 27. If he comes out on top, that would be a previously-Republican seat flipped for Democrats.

The Associated Press reports 80% of the vote on average has been counted across the state.

Arizona, 1 seat

Only one House seat remained up for grabs early Monday from the swing state of Arizona, which, overall, was finally called for Donald Trump over the weekend.

The seat in District 1 was still undecided, with an incumbent Republican candidate leading by less than 1%, according to the AP. .

Donald Trump wins Arizona and its 11 electoral votes, flipping the state red again

Alaska, 1 seat

The only district in Alaska was yet to be called Monday, District 1.

This seat seems likely to be another that could flip red, as Democratic incumbent Rep. Mary Peltola is trailing Republican Nick Begich.

Colorado, 1 seat

Colorado's seat in District 8 remained undecided early Monday, with Republican candidate Gabe Evans leading over the Democratic incumbent, Yadira Caraveo.

If Evans wins, this would be another seat flipped for the GOP.

Iowa, 1 seat

The seat in Iowa's 1st Congressional District is still up for grabs, with the incumbent GOP candidate leading.

Louisiana, 1 seat

The seat in Louisiana's 6th Congressional District is still undecided, with one of the Democratic candidates leading.

Maine, 1 seat

The seat in Maine's 2nd Congressional District was still not called, with the incumbent Democrat Jared Golden leading just slightly early Monday.

Ohio, 1 seat

Democratic incumbent Marcy Kaptur was leading in Ohio's 9th Congressional District on Monday.

Oregon, 1 seat

One seat in Oregon is yet to be determined, in the state's 5th Congressional District.

Democratic candidate Janelle Bynum was leading against the incumbent GOP, Lori Chavez-DeRemer. If Bynum pulls out a win, this would be a seat flipped for the Democrats.
