"Lots of those kinds of questions really can't be answered until November" King says. "I don't want to sound like I'm taking anything for granted, but I want to be able to assess all the circumstances, what the numbers are, what the break down is, what the opportunities for Maine are, and make that decision when the time comes."
Summers and Dill say they're aware of the advantages enjoyed by King, who polling shows is considerably ahead. But they maintain that the race is just getting started.
"Certainly, in a state like Maine I think politics is a much more personal endeavor," Summers said. "People expect to see you and tell you exactly what they think of you, but that's OK because what it does is you either get a thick skin and you learn how to be effective in the process, or you stop and you get out of it."
