HARTFORD, Conn. (AP) — Democratic U.S. Sen. Chris Murphy has won a second term in office, defeating a little-known Republican small businessman.

Murphy had amassed a war chest 100 times bigger than Matt Corey, who runs a high-rise window clean business in Hartford. It was a marked difference from his 2012 victory, when Murphy defeated former professional wrestling executive Linda McMahon, who spent about $50 million of her own money on the race.

The 45-year-old Murphy spent much of the campaign helping fellow Democrats. He also transferred $320,000 from his $14.5 million campaign fund to the state Democrats to help with field organizing.

Murphy has said he wanted to make sure Democrats were doing “everything possible to get the biggest turnout we could.”

Corey accused him of not taking the race seriously.
