While Republican Presidential hopeful Mitt Romney is working to defuse his comments about almost half of America being dependent on welfare, President Barack Obama has reached the 50 percent mark in some key swing states.

With just about seven weeks left before the general election on Nov. 6, a new Quinnipiac University/New York Times/CBS News poll released Wednesday shows Obama leading in the critical swing states of Wisconsin, Virginia and Colorado.

In Virginia, Obama leads 50 to 46 percent, and 51 to 45 percent in Wisconsin, the home state of Romney’s running mate Paul Ryan. The lead in Colorado is much slimmer though, 48 to 47, within the margin of statistical error.

The poll, conducted between Sept. 11 and Monday, shortly after the conventions, has a margin of error of a little over 2 percent in all three states.

On the issue of the economy – the most pressing at the moment – voters in all three states have both Obama and Romney tied as to who is better at handling it.

Obama emerged over Romney though on the handling of healthcare, Medicare and international crises – good news for the President as several countries in the Middle East continue to flare up over the “Innocence of Muslims” movie. Protests about the movie in Benghazi, Libya, were likely used as a cover by militants who attacked the U.S. consulate leading to the deaths of four Americans, including the U.S. ambassador to the country.

Voters in these states also put Obama on top as the candidate who cares more about their needs and problems.
