(NEW YORK) -- President Donald Trump is claiming “tremendous success" on Twitter -- even as his party loses control of the House to Democrats according to ABC News projections.
Democrats will pick up at least 23 seats. Meanwhile, Republicans will likely retain control of the Senate guaranteeing partisan showdowns and potential gridlock when the new Congress convenes next year.
Here's the latest:
1:48 a.m. ET -- Democrat Lauren Underwood will become the first black woman to represent her district, in Illinois’ predominately white 14th Congressional District, ABC News can project based off of exit polls.
1:37 a.m. ET -- 21 congressional districts voted for President Obama and then for President Trump. The GOP was able to hold down 12 of them in Congress. ABC News can project that Democrats will flip six of those seats.
1:30 a.m. ET -- In Georgia, a vote count error in the state has narrowed the lead of Republican candidate Brian Kemp over Democratic candidate Stacey Abrams. Kemp is just above the 50 percent threshold. If his share of the vote falls below 50 percent, Georgia law states that the race would go to a runoff.
The Abrams campaign said that they don't expect to concede tonight, and that they believe there are enough votes still outstanding to force a runoff.
"We are going to make sure every single vote is counted," Abrams said.
1:25 a.m. ET -- Democrat Lizzie Pannill Fletcher has defeated GOP Rep. John Culberson in Texas’ 7th Congressional District, which includes the Houston suburbs, ABC News can project.
1:00 a.m. ET -- In Maine, another governorship will likely flip in favor of Democrats at the gubernatorial level. Republican candidate Shawn Moody has conceded to Democratic candidate Janet Mills. ABC News has not yet projected a winner in the race.
12:49 a.m. ET -- The Democrats will pick up between 32 and 36 seats in the House, ABC News can project.
12:41 a.m. ET -- GOP Rep. Steve King has won re-election to Iowa’s 4th Congressional District, fending off Democratic challenger J.D. Scholten, ABC News can project.
12:38 a.m. ET -- Phoenix: The crowd at the Democratic Election Night party in Phoenix was buoyed by hope and lively music earlier in the night, but it's started to thin out as it seems more and more likely that the Arizona Senate race might be too close to call tonight.
The race between Democrat Rep. Kyrsten Sinema and Republican Rep. Martha McSally to fill Sen. Jeff Flake's seat is neck-and-neck.
Sinema supporter Michelle Rose predicted they'd have a winner by 11 p.m. MST / 1 a.m. EST, and Timothy Bradley said he thought it'd be either by 11 or 12 a.m. Ginny Doherty left a little more wiggle room, telling ABC News she thought it would be closer to 2 a.m. MST.
According to officials, those guesses could be way off.
Part of the problem is that there are still hundreds of thousands of votes that still need to be tabulated in the state's most populous county, Maricopa County, which includes Phoenix. Maricopa County Recorder Adrian Fontes told ABC News tonight that it could take up to a week or more for Maricopa to have their final results.
Sinema and McSally are battling it out for the Senate seat that's being left open by Sen. Jeff Flake's decision not to seek re-election.
Preliminary exit poll results suggest that Sinema is getting help by moderate Arizonans, with a 27 point margin that has her up 63 percent to McSally's 36 percent.
That appeal, and her perceived independent streak, is what drew Matt Winter to volunteer for Sinema.
"In recent history we’ve had John McCain and Jeff Flake and Republicans who have a strong independent streak, and she’s a Democrat with a strong independent streak," Winter told ABC News.
12:18 a.m. ET -- Whatever the results in any given election, the rise in diversity is nothing short of remarkable. In the 1990 midterm elections, the division of whites and nonwhite voters was 91-9 percent. Today it’s 72-28 percent. The most non whites voters ever in a midterm, and a scant 1 point shy of the record for any election in 2016. The Hispanic vote came in at 11 percent, again a new midterm high, and matched its all-time high from 2016.

11:48 p.m. ET -- Republican Josh Hawley has defeated Democratic Sen. Claire McCaskill, ABC News projects, based on analysis of voting data. McCaskill was one of the ten Democratic Senators running in states President Trump won in 2016.
McCaskill has conceded.
11:46 p.m. ET -- Sen. Heidi Heitkamp conceded to opponent Rep. Kevin Cramer in North Dakota's senate race. Heitkamp called North Dakota “a 36 point state,” the margin by which Trump won there in 2016, and said she knew it was an uphill battle from the start.
“We knew we were in a tough campaign. We knew we took some votes that people were critical of,” she said, an apparent reference to her vote against Justice Brett Kavanaugh’s confirmation to the Supreme Court.
But she never intended to “to rubber stamp any one party,” she said.
“This has been the honor of a lifetime,” she said, encouraging her supporters not to be bitter about the results.
11:41 p.m. ET -- In a strong display of the range of seats Democrats have been able to flip tonight, ABC News can project a win for the party in the deep red state of Oklahoma, in the state's 5th Congressional District.
Democrat Kendra Horn is projected to defeat incumbent GOP Rep. Steve Russell in another upset, based on vote analysis. The district is anchored by Oklahoma City but also includes more rural areas of the state.

Trump held rallies in West Virginia a whopping five times in an effort to turn a state he won by 42 points red all the way.
11:28 p.m. ET -- Although ABC News can project the senate race in North Dakota for Republican Kevin Cramer, Democratic incumbent Sen. Heidi Heitkamp hasn’t conceded just yet. Heitkamp's team says she's not watching the returns -- she’s out at the movies. Her choice tonight? According to her campaign: A Star is Born.

9:46 a.m. ET -- Mark Salter, longtime aide and speechwriter for the late Sen. John McCain, a Republican, urged his Twitter followers to "vote for the Democrat (in most cases).
"That feels weird to write," Salter tweeted. "But the bigger the rebuke of Trump the better for the country. Resist."
McCain was one of Trump's most outspoken Republican critics. The Arizona senator died in August at age 85 after a yearlong battle with brain cancer.
9:17 a.m. ET -- Former Secretary of State Hillary Clinton, the Democratic candidate who ran against Trump in the 2016 presidential election, made a final appeal to voters.
"For the past two years, we've watched this administration attack and undermine our democratic institutions and values. Today, we say enough," Clinton wrote in a series of tweets.
"But we won't just vote against radicalism, bigotry, and corruption today. We'll vote for fantastic candidates all over the country—including a historic number of women—who want to raise wages, fight for justice, and help more people get health care," she tweeted.
"If they win, they’ll do great things for America. Let's exercise our birthright as Americans today, put those people in office, and continue the hard work of saving our democracy. It'll take all of us. Happy Election Day."
7:43 a.m. ET -- Authorities in some states are warning voters to be vigilant about possible election problems.
The New Jersey Department of State urged residents via Twitter to beware of "false information regarding your polling locations."
High enthusiasm evident in early voting
The conversation ahead of the midterms has been dominated by talk of Democratic enthusiasm that could bring a "blue wave."
Democrats appear more poised for victory in the House, where they need a net gain of 23 seats to win the majority. In the Senate, Democrats would need a net pickup of two seats to take control, but there are 10 vulnerable Democratic senators running in states Trump won in 2016.
Early voting has also been read as a signal that enthusiasm is up -- though in some states, it's a result of newly-expanded early voting opportunities. According to data from Michael McDonald, an early-voting expert at the University of Florida, 2018 early voting has already significantly surpassed 2014 figures.
As of Friday, over 30 million early ballots were cast, compared to 17 million as of the same day in 2014.
According to the latest ABC News/Washington Post poll, the top issues driving voters this year are health care and the economy, which are almost tied in importance, followed by immigration. Democrats have made health care -- and especially coverage for people with pre-existing conditions -- a key part of their platform, while Trump has significantly upped his rhetoric on immigration, using a migrant caravan that's weeks away from the U.S. border to bring the topic to the forefront.
A diverse set of candidates
Despite ingrained partisan positions on these issues, the candidates running for election across the country this year are diverse, and many are poised to make history.
If elected, Democrat Stacey Abrams, running for governor in Georgia, will be the first African-American woman governor in U.S. history. Three other states south of the Mason-Dixon line could also elect their first-ever African-American governors.
It could be a historic year for Native American women as well. In the House, Sharice Davids of Kansas and Debra Haaland of New Mexico, both Democrats, could become the first Native American congresswomen. And, Paulette Jordan, a Democrat running for governor of Idaho, could become the country's first Native American governor, as well as her state's first female governor -- and its first Democratic governor since 1999.
There are also two female Muslim congressional candidates, Rashida Tlaib in Michigan and Ilhan Omar in Minnesota, who are poised to make history as well.
And Vermont is poised to make history for the LGBTQ community if voters in the Green Mountain State oust their current governor in favor of first-time candidate Christine Hallquist, who would be the first transgender governor in the nation if elected on Tuesday.
In some states, both candidates on the ticket offer diverse and historic choices.
In New Hampshire, Eddie Edwards, a Republican, would be the state’s first African-American member of Congress. His opponent, Democrat Chris Pappas, would be its first openly gay member of Congress.
And while many individual candidates could be historic change-makers, taken together, there are also some record-breaking numbers.
More women, for example, are running for Congress than ever seen before.
In the House currently, 84 of the 435 members are women, while a staggering 239 women are on the ballot Tuesday. They range from former fighter pilots to intelligence officers, doctors, nurses and scientists. By a 3-to-1 margin, the women candidates are Democrats.
Veterans are also on the ballot in record numbers. According to a nonpartisan veterans' super PAC, over 200 military veterans are running for Congress — a stark number considering there are fewer veterans in Congress today, at 20 percent, than ever before.
Polls in competitive races begin to close at 7 p.m. EDT and continue through 1 a.m. EDT.
After months of fundraising, advertising, door knocking and block walking, the candidates have made themselves known.
Now it's up to the voters.
