Following the 2018 midterm elections, the number of states with a split U.S. Senate delegation will drop from 14 to just 10 in 2019. This marks the fourth consecutive election with a decline. This is also just one above the historically low value* of nine split delegations set in 1955-56.
The chart below, from a Pew Research study, shows the totals by state for the past fifty years, ending before this year's midterms. After Democrat Doug Jones won a 2017 special election in Alabama, 14 states had a split delegation.
Democrat TJ Cox is the projected winner in California's 21st congressional district, defeating incumbent Republican David Valadao. This was the final House race to be called. Democrats have a net gain of 40 seats, and will hold a 235-200 edge on the GOP when the new House is seated during the first week of January.
It is over for Congressman David Valadao in #CA21. His best county's provisionals reported today, and broke for the Democrat, TJ Cox. Outstanding votes are going to be more of the same. That makes a forty seat gain for the Democratic Party in the House of Representatives.
Almost all media outlets had initially called the race for Valadao, who led by 8% on election night. However, his lead steadily shrunk as more votes were counted, and these same outlets were forced to retract that call. Cox took the lead for good two days ago.
Mississippi Republican Sen. Cindy Hyde-Smith won the state's special election runoff Tuesday. Appointed when former Sen. Thad Cochran resigned last spring, Hyde-Smith will now serve out the remainder of his term. The seat will be up again in 2020.
With this result, the 2018 Senate elections have come to a close. The GOP maintains control, with a net gain of two seats in the midterm elections. They will go into 2019 with a 53-47 edgea. Overall, six seats changed hands. Republicans won seats in Florida, Indiana, Missouri and North Dakota, while Democrats were able to take the seats in Arizona and Nevada.
Note that you may hear that Republicans gained one seat (not two) during this election cycle. This is accurate, with the difference attributable to the 2017 special election in Alabama that saw a Democratic gain.
The final seat in the U.S. Senate will be decided today as Mississippi holds a runoff election. Polls close at 7:00 PM local time (8:00 PM Eastern). Live results will be available in the table below after that time. Reload the page for the latest totals.
The runoff is between Republican Sen. Cindy Hyde-Smith and her Democratic challenger, former U.S. Rep. Mike Espy. It was necessitated when none of the four candidates in the November 6th special election received a majority of the vote.
Incumbent Rob Woodall prevailed by 433 votes after a recount in Georgia's 7th congressional district. At the time, this was the final uncalled race and it appeared Democrats would have a 234-201 advantage in January when the new House is seated.
However, late today, our results partner Decision Desk HQ retracted their earlier call of a GOP win in California's 21st congressional district. They say that race is now too close to call.
"Rep. Valadao’s lead has shrunk from over 4,900 and 8% on 11/7 to just over 400 with thousands of additional ballots left to count in areas favoring Cox. It is still quite possible for Valadao to hold his seat, but if he does, it will be by a very, very slim margin, certainly not the margin inferred on election night."
Our results partner, Decision Desk HQ has called Utah's 4th congressional district for Ben McAdams. This is the 39th pickup for the Democratic Party. Only one race - Georgia's 7th district - remains uncalled. Republican incumbent Rob Woodall is favored here; but the challenger Carolyn Bourdeaux has requested a recount.
Republican Will Hurd has won a 3rd term in the 23rd congressional district of Texas. While, the vote remains very close, his Democratic challenger Gina Ortiz Jones conceded on Monday.
Incumbent Democratic Sen. Bill Nelson conceded the Florida Senate race Sunday afternoon. Gov. Rick Scott prevailed after two rounds of recounts. Republicans have secured 52 Senate seats compared to 47 for Democrats, ensuring the party maintains control of the chamber. The Mississippi runoff election will decide the final seat.

July, 2019: Michigan Rep. Justin Amash resigned from the GOP to became an independent in July, 2019, breaking the tie in that state's delegation. It is now 7-6-1, with Democrats in the majority. Across the 50 states, Republicans have the majority in 26, Democrats 23, with one tie.
Original Article: 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.
