Democrats captured the House on Tuesday as Americans stampeded to the polls for a historic midterm that was as much a referendum on President Trump's policies and behavior as it was about control of Congress.
A simple House majority would be enough to impeach Trump if evidence surfaces he obstructed justice or that his 2016 campaign colluded with Russian Federation.
A Republican victory in both chambers of Congress would hand Trump a powerful mandate a month after he solidified a conservative majority on the Supreme Court when Senate confirmed his nominee, Brett Kavanaugh.
And Rep. Adam Schiff, slated to become chairman of the House Intelligence Committee, has vowed to probe alleged Trump campaign-Russia collusion. "Thank you to all!" "Certainly we feel good about where things are headed".
Almost 40 per cent of voters cast their ballots to express opposition to the president, according to AP VoteCast, a national survey of the electorate, while about 25 per cent said they voted to express support for Trump. Presidents nearly always lose seats in midterms - often regardless of the economy.
At stake are all 435 seats in the US House of Representatives and 35 of the 100 seats in the Senate. Early results showed Democrats winning pick-ups in congressional districts in Virginia, Florida, Pennsylvania, Colorado and New Jersey, as voters there sent a message of repudiation against Trump.
In Indiana, Republican Mike Braun knocked off Democratic Sen. She cited Mike Braun, who unseated Senate Democratic incumbent Joe Donnelly in IN and helped cement a Republican majority in the upper chamber, and who benefited from three Trump rallies on his behalf.
In Texas, Republican Ted Cruz Cruz beat his challenger, Democratic rising star Beto O'Rourke. Both Republicans Rick Scott in the Senate race and Ron DeSantis in the governor's race hold leads in Florida.More news: Ariana Grande Has Created the Perfect Breakup Anthem

In the lead-up to the election, Republicans privately expressed confidence in their narrow Senate majority but feared the House could slip away. Democratic Senator Sherrod Brown held his seat in Ohio.
Voter Ontaria Woods said about two dozen people who had come to vote left because of the lines.
Trump himself noted the energy as he wrapped up a punishing schedule of rallies around the country that were meant to boost Republican candidates - and his own brand heading towards reelection in 2020.
The TV channel's earlier estimates gave 230 House seats to the Democrats.
The crucial polls, marking the first major voter test of Trump, is seen as a referendum on his controversial policies, including those on immigration. It has lost ground among women, suburban voters, voters with college degrees, while showing little ability to win over young and minority voters.
The governor focused much of his campaign on his opposition to President Donald Trump and Trump's policies, and he continued that in his victory speech, at times addressing the president directly, saying NY is not "buying" what Trump is selling.
Cook said Democrats have a possibility of gaining as few as 20 seats and as many as 45 seats.
With divided leadership in Congress and a president who has taken an expansive view of executive power, Washington could be in store for even deeper political polarization and legislative gridlock. Among those expected were Trump's adult children, White House aides, Republican officials and presidential friends.
Investors often favor Washington gridlock because it preserves the status quo and reduces uncertainty, even though many investors this time around had been hoping for a continuation of the Republican agenda.
