WASHINGTON (AP) - Add this to your set of Election Day unknowns: Control of the United States Senate could conceivably come down to an independent candidate from Maine who has resolutely refused to say which party he'd side with if voters send him to Washington.
While it's commonly accepted that Angus King, a former Democrat who supports President Barack Obama, would align with Democrats, he has refused to say. That's generated suspense and, in theory, could translate to power if the Senate ends up close to a 50/50 split. If one party wins a decisive majority, King may find he has less leverage than he hopes.
Which party wields power after Election Day is all about the math, but the answers may not be immediately clear.
