According to a new Quinnipiac University/CBS News/New York Times poll, President Obama leads Republican challenger Mitt Romney by significant margins in the swing states of Ohio, Florida, and Pennsylvania.

Support for Romney among whites and men has dropped slightly, while the president continues to hold an 87 to 11 percent lead among nonwhites. More than two-thirds of Hispanic voters are expected to cast ballots for Obama.

Two-thirds of likely voters in Florida support the deferred action policies put in place recently by the Obama administration. 66 percent of Florida likely voters say they support the DREAM Act, a number that jumps to 80 percent among likely Hispanic voters.

Obama leads Romney 53 to 43 percent in Ohio, 53 to 44 percent in Florida, and 54 to 42 percent in Pennsylvania, according to the poll. He has widened the Ohio lead to 10 points from six points just one month ago. The president also leads in all three states on every issue but the budget deficit, including immigration.
