As the last day of campaigning nears its close, Scott Brown and Martha Coakley have taken off the gloves while they fight for Ted Kennedy's old spot in the Senate. A Politico poll shows Brown leading with 52 percent against Coakley's 43, and other polls find him "surging" ahead. Coakley’s backers accused Brown of smiling at a violent remark made by a supporter (he asked Brown to “shove a curling iron up [Coakley’s] butt”), and Brown lashed back by accusing Coakley of using a Martin Luther King Day celebration they both attended as a chance to campaign instead of celebrate the man’s legacy. (Martin Luther King III endorsed Coakley in a video, and said it was appropriate that she was campaigning.) "Democrats have full reason to be frantic," says Politco.
