iStock/Thinkstock(NEW YORK) — After spending all day at the polls, voters could begin to see midterm election results within hours.
Preliminary results from the national exit poll are out, and the first polls begin to close at 6 p.m. ET.
This year’s midterms are the first nationwide contests since 2016, when President Donald Trump was elected. Many, including the president himself, see this election as a referendum on his presidency.
"I'm not on the ticket, but I am on the ticket because this is also a referendum about me," Trump said at a rally in Southaven, Miss., in early October.
With Republicans currently in control of the White House and both chambers of Congress, 35 Senate seats, all 435 seats in the House and 36 governorships are on the ballot. The Election Day 2018 Live Map shows when polls close around the country and, as votes get counted, will give hourly state-by-state results for the Senate, House and governorships.
Here's the latest:
5:59 p.m. ET — President Donald Trump and which party controls Congress are front and center for voters this election year, according to preliminary results from the national exit poll.
In results so far, 44 percent of voters approve of Trump’s job performance, while 55 percent disapprove.
And while the House races will be fought district by district, voters by 53-43 percent say they’d rather see the Democrats than the Republicans in control of the House after this election.

4:34 p.m. ET — Dozens of young Native Americans marched to their local polling place on a reservation near Belcourt, North Dakota.
The group of young men and women, members of the Turtle Mountain Band of Chippewa, carried signs that read, "Don’t disenfranchise us," as they chanted in unison, "North Dakota, you can’t do that!"
By the time they reached the polls, more than a thousand people had already cast ballots hours before the polls were to close. In comparison, just 950 people voted at the same polling site in 2016, according to an election official there.
Tribal leaders have scrambled to print at least 3,500 new tribal IDs for Native Americans on reservations in North Dakota in response to the state’s new voter ID law, which requires North Dakotans to provide a state or tribal ID with a residential address in order to vote. Many Native Americans living in rural communities on or near reservations don’t have residential addresses.
4:21 p.m. ET — The issues with electronic poll books in Indiana's Johnson County have been "resolved," election officials said.
The midsize county, which is located south of Indianapolis, will not be extending voting hours but officials will add more voting machines if need be, according to Johnson County election board chairman Phil Barrow.
Election Systems & Software, the electronic voting vendor the county employs, also confirmed in a statement that the issues were fixed.
"The issue in Johnson County, Indiana has been resolved, resulting in faster check-in times for voters," the company said in a statement Tuesday. "Earlier in the day, the poll book, which is used to check in voters but is not related to voting machines themselves, was running slowly. The poll book operation is now significantly improved. We apologize to voters and to elections officials in Johnson County, Indiana for longer wait times than expected, and we thank everyone for their patience."
Johnson County is in a congressional district considered safe for Republicans, but the Senate race in Indiana is considered competitive, with Democratic incumbent Joe Donnelly trying to beat back a challenge by Republican Mike Braun.

3:19 p.m. ET — Multiple high-ranking sources in the White House and outside advisers close to President Trump say they are bracing for an interesting evening – all the sources believe it is most likely the House will be in the hands of Democrats after tonight’s results.
One source said the reality is if there is good news tonight for Republicans, the president will take all the credit; however, he already knows he will get blamed if it’s not a great night.
2:52 p.m. ET — Electronic poll books were malfunctioning temporarily on Election Day in Johnson County, a midsize Indiana county south of Indianapolis.

Johnson County is in a congressional district considered safe for Republicans, with incumbent GOP Rep. Trey Hollingsworth expected to hold his seat against Democrat Liz Watson.
But the Senate race in Indiana is considered competitive, with Democratic incumbent Joe Donnelly trying to beat back a challenge by Republican Mike Braun.
2:27 p.m. ET — Outgoing Republican Rep. Darrell Issa of California, who did not run for re-election, predicted a Democrat would win his seat.

When ballots cannot be ready by tabulators, they are stored securely in 'emergency bins' and will be tabulated as soon as possible," the board said in a statement Tuesday morning. "All ballots will be counted."

10:03 a.m. ET — Newspapers across the U.S. splashed headlines conveying some of the emotion and tension around this election.
Here are a few of them.
– The Columbus Dispatch: "It's up to you now"
– Connecticut Post: "Midterm mania grips nation"
– Chicago Tribune: "A fight for control"
– The Des Moines Register: "IT'S DECISION DAY"
– The Detroit News: "Battle for Congress spirited until the end"
– Houston Chronicle: "DAY OF RECKONING IS HERE"
– Los Angeles Times: "Trump's reputation is on the line"
– New York Daily News: "YOUR CALL, AMERICA

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.
