WASHINGTON (AP) — Senate races in Florida and Arizona were too close to call Wednesday, raising the possibility of President Donald Trump gaining a more comfortable Senate majority.
Meanwhile, the outcomes in two races for governor, including a high-profile contest in Georgia, and several campaigns for Congress remained uncertain, with ballots still being counted in California and Washington state and races that haven't been called in Maine, New Jersey, Minnesota, New Mexico, Texas and Utah.
Here's a look at the races still undecided after Tuesday's midterm elections:
The showdown between Democratic Sen. Bill Nelson and Republican Gov. Rick Scott was still too close to call.
Nelson, who was first elected to the Senate in 2000, declined to concede the election and his campaign said it was preparing for a recount.
On Wednesday afternoon, Scott had a lead of less than one half of 1 percent. Election officials said early votes were still being tabulated in some counties.
Under state law in Florida, a recount is mandatory if the winning candidate's margin is less than 0.5 percentage points.
The Associated Press does not call any race that may proceed to a recount.
Republican Martha McSally and Democrat Kysten Sinema were also locked in a tight race. McSally had a slight edge on Wednesday afternoon, leading by a margin of less than 1 percent. Election officials planned to update the count later Wednesday and in the coming days. Roughly 25 percent of votes in Arizona are counted after Election Day.
Whoever emerges will become the first woman elected to the Senate from Arizona. McSally and Sinema are battling over the seat vacated by Sen. Jeff Flake, a Republican critic of Trump who decided not to run for re-election.
The race for governor in Georgia between Democrat Stacey Abrams and Republican Brian Kemp was too close to call.
With more than 3.8 million votes counted, Kemp stood at 50.4 percent, enough for an outright victory under a state law requiring a majority to win a general election without a runoff. But Abrams and Kemp were both awaiting absentee, mail-in and provisional ballots left to be counted.
On Wednesday afternoon, Kemp lead by a margin of 1.7 percentage points. However, election officials said tabulation continued in several large counties.
In Alaska, the race for governor between Republican Mike Dunleavy and Democrat Mark Begich was too early to call.
On Wednesday afternoon, Dunleavy led by 7.5 percentage points. But roughly 20 percent of votes in Alaska are counted after Election Day.
Dunleavy, a conservative former state senator, declared victory in the race. The AP has not yet called the race. Dunleavy was the presumed front-runner for much of the race until mid-October when Gov. Bill Walker, an independent, ended his campaign days after Lt. Gov. Byron Mallott resigned over what Walker described as an inappropriate overture to a woman.
Begich is a former Anchorage mayor and one-term U.S. senator. For much of the campaign, there was angst among some Democrats and independents who feared he and Walker would split the vote and hand the race to Dunleavy.
Nearly 20 races for the House remained too close to call, with the outcomes uncertain in states such as California, New York, Georgia, New Jersey and Washington state.
Rep. Ben Ray Lujan, D-N.M., the chairman of the House Democrats' campaign arm, said House Democrats were still counting ballots and assessing races too close to call. The AP has not called six races in California, including four in the one-time Republican stronghold of Orange County.
In Georgia, the races of Republican Reps. Karen Handel and Rob Woodall remained too close to declare a winner and the campaigns said absentee ballots were still being counted. Lucy McBath, the Democrat challenging Handel, tweeted that "this race is far from over."
In Utah, Republican Rep. Mia Love trailed her Democratic challenger Ben McAdams based on his strong showing in his home county of Salt Lake County. But Love hoped to flip the deficit by winning a large portion of the votes left to be counted in her stronghold of Utah County, where long polling lines led to slow vote tallies.
