PORTLAND, Maine - A rematch between Republican Rep. Bruce Poliquin and Democrat Emily Cain has brought record spending to Maine's 2nd Congressional District.
Poliquin, who won two years ago, casts his opponent as a career politician who supports higher taxes and who's out of touch with Mainers. Cain, meanwhile, accuses Poliquin of being a multimillionaire puppet of Wall Street donors who abused tax loopholes in Maine.
The campaign has been targeted by both parties. The two candidates together raised more than $6 million, and the race has attracted more $9 million in outside spending.
In the 1st Congressional District, Democratic U.S. Rep. Chellie Pingree faces a political newcomer, Republican Mark Holbrook, in her bid for a fifth term.
