Maine has been caucusing all week (who knew, right?) the results of which will be announced Saturday night. The turnout for Maine's caucuses are typically very low, making the results unpredictable and giving Ron Paul a real chance at his first primary win this year. Paul has been campaigning ferociously in Vacationland this week and plans to stay until the results are called. Mitt Romney, on the other hand, will arrive in Portland on Friday night for his first campaign in the state this year—though he did win the Maine caucuses in 2008.
