FILE – In this Aug. 18, 2014 file photo, Sen. Angus King, I-Maine speaks in Portland, Maine. After millions of Americans vote next week, after billions were spent to win those votes, could it be that control of the Senate ultimately comes down to the whims of … Angus King? Or a Senate rookie named Greg Orman? Both are independents, and if the math falls just right on Election Day, which party they decided to side with in the chamber will decide which party takes control in the next Congress.
