As the returns come in, there are some critical counties to watch. The two primary swing areas are Arapahoe County and Jefferson County--and the turnout there could make the difference.
Beyond that, there are a few other key counties that folks on both sides of the aisle need to watch. As is to be expected, above-average turnout in Denver, Boulder and Pueblo could secure a victory for Obama. On the other hand, high turnout in Douglas, Broomfield, Mesa, Weld and El Paso could mean a victory for McCain.
