With Republican Sen. Olympia Snowe's announcement that she won't seek a fourth term, a number of Maine Republicans and Democrats are considering jumping into the Senate race.
Four Democrats who already announced they're running could be joined by U.S. Reps. Mike Michaud and Chellie Pingree, both of whom say they're weighing a bid for the open seat.
On the Republican side, small-business owner Scott D'Amboise (dam-BOYZ') is the only candidate for now. He says he's the presumptive nominee because others have only until March 15 to collect 2,000 signatures to qualify for the ballot.
But other Republicans may jump in after Snowe's surprise announcement on Tuesday. Maine Senate President Kevin Raye, who's running for Maine's 2nd Congressional District seat, said he'll consider a Senate bid.
