Of all the victories for Senate Republicans, Ms. Collins stood out as the most notable. Facing a wave of Liberal outrage over her 2018 vote to uphold Supreme Court Justice Brett M. Kavanaugh amid sexual assault charges, she followed House Speaker Sara Gideon representatives from Maine, in the final weeks of the race.
In the end, she proved that she was one of the few senators in the country still capable of exceeding the top of the ticket significantly, winning her fifth term even as Mr. Trump lost badly in Maine to Mr. Biden. .
Yet already with the prospect of a Senate election in 2022 on more difficult terrain for Republicans, Mr McConnell suggested there were reasons the party was worried as well.
Speaking to reporters after his own dominant victory in Kentucky, he said Republicans had urgent work to do to win back the support of women and college graduates voters, as well as to strengthen their fundraising apparatus. , which has lagged behind the Democrats’ juggernaut, ActBlue.
“I am troubled by the loss of support in the suburbs of the country,” said Mr. McConnell.
Democrats remained optimistic about the races in Georgia. Rev. Dr. Raphael G. Warnock, a Democrat, was heading for a second round in January against Senator Kelly Loeffler, the Republican-nominee, in a special election to replace Senator Johnny Isakson, who retired in late 2019 due to health problems. Documentary filmmaker Jon Ossoff, 33, was in a tight race to topple Mr Perdue, who could also end up in a runoff if neither crossed the 50% threshold required by law Georgian to win.
Both sides had other goals outstanding, but they were seen as chunks. For Republicans, the best option was Michigan, where John James, a black Iraq war veteran who unsuccessfully ran for the Senate in 2018, was trying to topple Sen. Gary Peters. Democrats still believed they had an outside chance of defeating Sen. Dan Sullivan in Alaska.
