Vice President Biden is going West to rally Democrats in the final sprint before the Nov. 6 election. With stops in Colorado and Nevada Wednesday and Thursday, Biden will frame what the Obama-Biden campaign calls “the choice between moving our country forward with an economy built to last from the middle out or returning to top-down economics that failed families.”

Polls in Colorado and Nevada show a close competition between the two candidates, just as national polls show a tightening race.

This week, a USA Today/Gallup Poll of swing states showed Romney gaining with female voters. A Denver Post survey following the first presidential debate, which was held in Denver, showed Romney gaining significantly and pulling the race to a statistical tie in Colorado.

In Nevada, most polls show Obama with lead of one or two percentage points.

At the vice president's most recent campaign rally, Friday in Wisconsin, he focused on women’s issues, the war in Afghanistan and tax policy.
