MADISON, Wis. (AP) -- Democrat Barack Obama is leading Republican John McCain by 13 points in Wisconsin according to a new poll.
The poll released today by Quinnipiac University in Connecticut also shows Obama ahead in Minnesota, Colorado and Michigan.
In Wisconsin, Obama is favored by 52 percent of those polled compared with 39 percent for McCain.
Because the Wisconsin race has been so close in the past two presidential elections, the state is widely expected to be among a handful where both candidates believe they can win.
The random telephone poll of more than 1,500 likely voters in Wisconsin was conducted between June 17 and June 24 with a margin of error of plus or minus 2.5 percentage points.
