First-term Republican U.S. Rep. Bruce Poliquin defeated Democratic former State Senator Emily Cain in the 2nd Congressional District race.
In the 1st Congressional District, Democratic U.S. Rep. Chellie Pingree defeated political newcomer, Republican Mark Holbrook, in her bid for a fifth term.
The District 2 election was a rematch between Poliquin and Cain and brought record spending to Maine's 2nd Congressional District. Poliquin, who won two years ago, casted his opponent as a career politician who supports higher taxes and who's out of touch with Mainers. Cain, meanwhile, accused Poliquin of being a multimillionaire puppet of Wall Street donors who abused tax loopholes in Maine. The two candidates together raised more than $6 million, and the race attracted more $9 million in outside spending.
