Montana Democrat Jon Tester has won a third Senate term, beating Republican Matt Rosendale, the state auditor.
President Donald Trump had taken a personal interest in defeating Tester, and had visited the state to campaign against the incumbent. Trump had said he wanted to make Tester pay at the polls for helping detail Trump's first nominee to lead the Department of Veterans Affairs.
Tester is the top Democrat on the Senate Veterans' Affairs Committee.
Tester insisted that Montana voters across the political spectrum would support him after examining his record.
Trump held four rallies in Montana and sent his eldest son and Vice President Mike Pence to headline more appearances. Rosendale also got help from outside cash that poured into the race.
There was also a winner in the race for Connecticut governor, and it's Democratic businessman Ned Lamont.
The 64-year-old cable TV company founder has prevailed over Republican businessman Bob Stefanowski. Lamont's victory means the seat stays in Democratic hands, with the Democratic incumbent, Dannel Malloy, set to leave office.
Lamont has promised to be a ``firewall'' against the policies of President Donald Trump.
Lamont poured more than $12 million of his own money into the hotly contest race.
He'd run for office before, losing bids for the Senate in 2006 and for governor in 2010.
Lamont's win completes a Democratic sweep of the top offices on the ballot in Connecticut, including the re-election of Sen. Chris Murphy
