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

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

If Republicans retain the majority in the House of Representatives, the Republican Party would gain control of all three branches of government. Control of the Senate has already been decided – turning away from the Democrats – and there are calls for a presidential victory for Donald Trump.

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

Here’s a quick look at which seats have already been turned and what remains to be mentioned:

Which House seats have flipped?

So far, Republicans have flipped, gaining three seats, according to race calls from The Associated Press. They all came from major theaters of war.

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 remained 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 need just four more seats to gain a majority, and were leading Monday in nine of the races yet to be called.

These are the races in question:

California, 10 seats

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

Republicans lead in four of those races (Districts 13, 22, 41 and 45), while Democrats lead 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 that would be flipped to Democrats.

The Associated Press reports that an average of 80% of votes have been counted across the state.

Arizona, 1 seat

Only one seat in the House of Representatives was up for grabs early Monday in the swing state of Arizona, which is generally was finally called for Donald Trump this weekend.

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

Alaska, 1 seat

The only district in Alaska had yet to be called District 1 on Monday.

This seat seems likely another seat that could turn red, as incumbent Democratic Rep. Mary Peltola trails Republican Nick Begich.

Colorado, 1 seat

Colorado’s District 8 seat remained undecided Monday morning, with Republican candidate Gabe Evans leading over Democratic incumbent Yadira Caraveo.

If Evans wins, this would be a new seat for the Republican Party.

Iowa, 1 seat

The seat in Iowa’s 1st congressional district is still up for grabs, with the incumbent Republican candidate in the lead.

Louisiana, 1 seat

The seat in Louisiana’s 6th Congressional District remains undecided, with one of the Democratic candidates in the lead.

Maine, 1 seat

The seat in Maine’s 2nd Congressional District had still not been declared, with incumbent Democrat Jared Golden taking the lead just a little earlier on Monday.

Ohio, 1 seat

Democratic incumbent Marcy Kaptur held the lead in Ohio’s 9th Congressional District on Monday.

Oregon, 1 seat

One seat in Oregon remains to be determined, in the state’s 5th Congressional District.

Democratic candidate Janelle Bynum was leading against Republican incumbent Lori Chavez-DeRemer. If Bynum wins, this would be a seat that flips for Democrats.

Washington, 1 seat

Washington’s remaining seat is guaranteed to go to the Republicans, as both candidates were in the Republican Party. The incumbent candidate was in charge.
