Biden blitzing Colorado on 2nd day of early voting

GREELEY, Colo. -- Democratic vice presidential candidate Joe Biden is beginning a blitz of communities along Colorado's Front Range on the second day of early voting statewide.

Biden begins his tour at the University of Northern Colorado in Greeley on Tuesday and will visit Commerce City, a northeast Denver suburb, later in the day.

On Wednesday, he has rallies in Colorado Springs and Pueblo.

Biden's tour comes on the heels of a one-day visit by GOP vice presidential candidate Sarah Palin, who campaigned in Colorado Springs, Loveland and Grand Junction on Monday.

Both campaigns are courting Colorado, whose nine electoral votes are up for grabs and could sway a close election
