Warren defeats Brown in Massachusetts, in latest Dem Senate victory Democrat Elizabeth Warren ousted Republican incumbent Sen. Scott Brown in the Massachusetts Senate election Tuesday night, Fox News projects, ending probably one of the most dramatic Senate races of the 2012 cycle. The win came on top of several significant victories for the Democrats, who are so far maintaining their slim-but-steady lead in the Senate. "Tonight is a great night for the people of Massachusetts and for the middle class across the country," Sen. Patty Murray, chairwoman of the Democratic Senatorial Campaign Committee, said in a statement. The win in Massachusetts joins a string of victories for the Democrats, including Rep. Chris Murphy winning an open seat in Connecticut over wrestling magnate Republican Linda McMahon; Democrat Joe Donnelly beating Republican Sen. Richard Mourdock in Indiana; and Rep. Tammy Baldwin beating Republican Tommy Thompson for the open Senate seat in Wisconsin. Democrats had a 53-47 Senate majority going into the election. Defying the odds and campaigning around the state in a pickup truck in 2010, Brown drew national attention as he captured the seat left by the late Democratic Sen. Ted Kennedy. He quickly became an icon in the party, seen as a rising star with broad appeal. But since his election, Brown has settled into the Senate as a more moderate figure, much like his New England counterpart, Sen. Olympia Snow, R-Maine, who retired this year out of disgust with the partisanship she said became untenable on Capitol Hill. Brown's move to the center did not help enough it seems, as Harvard professor Warren was able to defeat him into a tight, high-pitched contest, considered a toss-up for months.
