Democrat Stacey Abrams effectively conceded defeat Friday afternoon, acknowledging that Republican Brian Kemp will be Georgia's next governor.  All 36 gubernatorial elections have now been called by our results partner, Decision Desk HQ.

Prior to the election, Republicans held 33 of the 50 governorships, with 16 Democrats and 1 independent holding the remaining seats. Democrats flipped seven seats, winning Republican-held seats in Illinois, Kansas, Maine, Michigan, New Mexico, Nevada and Wisconsin. The lone GOP gain came in Alaska.

Next year will see gubernatorial elections in Kentucky, Louisiana and Mississippi. First term governors Matt Bevin (R, KY) and John Bel Edwards (D, LA) are expected to seek re-election. Gov. Phil Bryant (R) is term-limited in Mississippi. The 2019 elections will be held on Tuesday, November 5th.

Although a handful of districts remain uncalled, we now know which party will be in the majority in each state's 2019 U.S. House delegation. Republicans will have the majority in 26 states, while Democrats will have the most members in 22.  Two states, Michigan and Pennsylvania will be tied.  The concentration of Democratic districts in a small number of states gives the GOP a structural advantage in this count. They will hold the lead despite a Democratic majority overall.

However, this marks a significant improvement for Democrats relative to the current House, in which the GOP has a partisan edge in 32 states to 17, with Maine the lone tie. Come January, Democrats will be in the majority in five additional delegations: Arizona, Colorado, Iowa, Maine and Virginia. 

That's nice info, but who cares?  The count would come into play if a presidential election ended with no candidate reaching 270 electoral votes. In that case, the House would select the president, with each state receiving one vote. Note that should this occur with the 2020 election, it is the House elected in November, 2020 that would take the vote. The partisan distribution by state could be totally different after the next election, of course.

Here's the data in a Google Sheet.

Democrat Jared Golden has defeated incumbent Republican Bruce Poliquin in the closely-contested race for Maine's 2nd congressional district.  Golden prevailed via the state's ranked-choice voting process, which kicked in when none of the candidates received a majority of the initial vote in this four-person race.

Maine's largely rural 2nd district - the largest by area in the Eastern Time Zone - went for Donald Trump by 10 point in 2016. This earned the president an electoral vote in the state, which is one of only two that uses an allocation method other than winner take all.

Democrats now have 231 seats, Republicans 199, with five contests remaining undecided.

The 2020 electoral battleground map starts out much broader than in any presidential contest since 1992, according to an analysis in the Axios AM Newsletter on November 15th, 2018. "To win re-election, President Trump must wage a two-front war: Not only does he have to defend Democratic-leaning Midwest states that sealed his victory in 2016, but he now needs to defend against clear Republican erosion in the South and Southwest."

Doug Sosnik, who did the analysis, says "Changing demographicsand Trump have blown up the electoral map that has dominated American politics since 1992."

Democrat Andy Kim will win in New Jersey's 3rd congressional district. The election was called Wednesday afternoon by our results partner Decision Desk HQ, as well as by the Associated Press. This is the 230th seat won by Democrats, a net gain of 35. Six races remain uncalled.

In our pre-election New Jersey House overview, we noted that "If Democrats have a particularly good night, 19 term Rep. Christopher Smith (NJ-4) may be the only Republican in the New Jersey House delegation in 2019."  With Kim's victory, that will indeed be the case. 

Democrat Josh Harder is the projected winner in California's 10th congressional district. He defeated four-term incumbent Republican Jeff Denham. This marks the 34th net gain for Democrats in the House midterm elections, giving them 229 seats.  Republicans currently have 199, with 7 seats remaining to be decided.

This is the fourth gain for Democrats in California, giving them a 43 to 8 margin in the state's 53-person House delegation. The 39th and 45th districts remain uncalled.  These are both GOP-held seats in the Los Angeles area.

The Associated Press projects Democrat Kyrsten Sinema to win the closely-contested Arizona Senate race.

After this call, Republicans hold 51 Senate seats, Democrats 47, with two races remaining undecided.  Those are in Florida and Mississippi.  In Florida, Sen. Bill Nelson and his GOP challenger, Rick Scott, are separated by less than 0.25%, with a contentious recount underway. The Mississippi race is a special election, and will be decided in a runoff on November 27th.

U.S. Senate and Governor

As the vote count continues, Democrat Kyrsten Sinema has taken a small lead over Republican Martha McSally in the Arizona Senate race. Several hundred thousand ballots sent by mail are dropped off on Election Day, and these take time to be counted. Overall, approximately 400,000 ballots remain to be tallied.

Arizona U.S. Senate

Elsewhere, Florida's Senate race is likely headed for a hand recount, with the margin under 0.25%, while the gubernatorial race may get a machine recount, with a margin of under 0.50%. The Associated Press, as well as our results partner, Decision Desk, called the gubernatorial race for Ron DeSantis, and Democrat Andrew Gillum has conceded. A machine recount isn't likely to change that outcome, although this is Florida so one can never be sure.  

Things are a bit less clear on the Senate side, with the closer total and the prospect of a hand recount. The Associated Press has not called this race, and Nelson has not conceded. Decision Desk has called the race for Scott, and you will see that in the Florida vote counts. However, we have left the state undecided in our interactive 2018 Actual Senate map.

Meanwhile, the gubernatorial race in Georgia remains undecided. Republican Brian Kemp resigned as secretary of state Thursday. Kemp has 50.3% of the vote, to 48.7% for Stacey Abrams. As we've previously noted, the issue here is not whether Kemp will have the most votes, but rather whether he will stay above the 50% threshold needed to avoid a December runoff.

U.S. House

Four more races were called overnight, leaving 10 undecided. GA-6, MI-8 and NJ-7 went to Democrats, while IL-13 was won by the GOP. Democrats have now won 227 seats, Republicans 198. That's a net gain of 32 for Democrats. All 10 of the undecided races are currently held by the GOP. (Vote Counts for Uncalled Races >>).

In a surprising turn of events, Democrat Xochitl Torres Small has won in New Mexico's 2nd congressional district. The Republican nominee, Yvette Herrell had led on Election Night, with numerous media outlets declaring her the winner. However, absentee ballots counted Wednesday were heavily weighted toward Torres Small, putting her over the top.

Democrats have now won 224 seats, Republicans 197, with 14 remaining uncalled. That's a net gain of 29 for Democrats. All 14 of the undecided races are currently held by the GOP. (Vote Counts for Uncalled Races >>).

U.S. House

Democrats will have control of this branch of Congress beginning in January. As of this writing, they have won 220 seats, more than the 218 needed for a majority. Republicans have won 197. 18 districts remain uncalled.  All but one of the remaining seats is currently held by the GOP.  If you'd like to game out the remaining seats, here's an interactive House map based on actual results.

U.S. Senate

Republicans started the night with 51 seats and they'll have at least that many heading into 2019. Democratic incumbents Joe Donnelly (Indiana), Claire McCaskill (Missouri) and Heidi Heitkamp (North Dakota) went down to defeat. Democrats picked up Nevada.

On the map below, Florida is awarded to Republican Rick Scott, while California is not yet called. These are calls (or non-calls) made by our results partner, Decision Desk. Scott is ahead, but there remains the possibility of a recount. In California, there are two Democrats on the ballot. While a nominee call has not been made, Democrats will retain that seat.  On our interactive Senate map of actual results, we've awarded California, while keeping Florida undecided. 

The other two uncalled races are Arizona and the special election in Mississippi. In Arizona, Rep. Martha McSally (R) has a lead of just under 1% with over 99% of the vote in. Meanwhile, as expected, Mississippi's race is headed to a November 27th runoff.

Governor

Democrats have won six Republican-held seats, significantly cutting into the latter’s 33-16 edge heading into Election Day. Connecticut and Georgia remain undecided, although the Associated Press has called it for Democrat Ned Lamont. We show that on our interactive Governor map of actual results.

In Georgia, Republican Brian Kemp has 50.6% of the vote, a lead of about 2 points. The question at this point is not whether Kemp will finish with more votes than Democrat Stacey Abrams, but rather whether Kemp will finish above the 50% threshold to avoid a runoff on December 4^th.
