Obama leads Romney in key swing states: Virginia, Wisconsin, Colorado

President Barack Obama has taken the lead over Republican challenger Mitt Romney in Virginia, Wisconsin and Colorado, all crucial swing states in November's election, a new Quinnipiac University/CBS News/New York Times poll reported.

CBS News said Obama has a six-point advantage among likely voters in Wisconsin, the home of Republican Vice Presidential nominee Paul Ryan.

According to the New York Times, Wisconsin voters think Obama would do a better job with the economy. The President also maintains a 17-point lead when asked who cares more about their problems. 

Virginia, a key Southern stronghold, now has Obama in a four-point lead over Romney: 50 percent to 46 percent, the poll showed.

CBS News noted Obama was the first Democrat to carry the state since 1964, which traditionally votes Republican.

The race in Colorado, however, is the closest of the states surveyed. With a mere one-point lead, 48 percent to 47 percent, it's much too close to call. The poll has a three-point margin of error.
