A new MassINC Polling Group political survey (June 13-14; 506 likely Maine voters for television station WBUR) gives Independent former governor Angus King a huge 50-23-9 percent lead over newly nominated Republican candidate Charlie Summers and Democrat Cynthia Dill, respectively.
The Maine Senate race could become nation’s most important, because there are two scenarios where King alone would decide if Republicans or Democrats control the majority in the next Congress, should he be elected. To date, the former governor, though a liberal, has not committed to joining either party. Should President Obama be re-elected and Senate Republicans reach 50, King caucusing with either side would make that party the majority. The same would be true if Mitt Romney unseats the President and the Democrats claim 50 seats.
State Sen. Dill has the most difficult path to victory in the three-way scenario. According to the MassINC data, Democrats choose King 60-17 percent over the now-official Democratic nominee. Interestingly, his mark among Democrats is even better than within the Independent sample cell. Of those claiming to affiliate with neither party, King records 57 percent. Though his margin is strong, it is not insurmountable, particularly in a three-way race. Gov. Paul LePage (R) was elected from a similar configuration two years ago with just 37.6 percent of the vote. If the Senate majority truly reverberates on Maine’s outcome, then expect the race to become heated as Election Day nears.
