Democratic U.S. Sen. Michael Bennet of Colorado has won re-election to a second full term, defeating Republican challenger Darryl Glenn.
Bennet once was considered one of the most vulnerable Senate Democrats this year. But Glenn, a tea-party-aligned conservative from El Paso County, struggled to raise funds after national party leaders refused to endorse his candidacy.
Glenn also baffled many with his changing positions on whether he still endorsed Donald Trump after the disclosure of Trump's lewd remarks about women last month.
Bennet raised millions early in his campaign and stressed his record of working with Republicans on such issues as funding for Zika virus research.
