The Massachusetts Democrat, first elected in 1980, serves as the ranking Democrat on the House Financial Services Committee. During a four-year stint as chairman of the panel, he helped shepherd the Dodd-Frank overhaul of the nation's financial regulations.
He won a closer-than-expected re-election bid in 2010, taking 53 percent of the vote, his lowest total since first winning his Newton- and Taunton-based district in 1980.
