Obama vs. Romney: Who really has the momentum?

It’s tough to say how the presidential candidates stand in the polls. Surveys show Romney pulled ahead after the first debate, but poll data show he’s lost some of that ground in other areas since then. Two new polls show President Obama ahead in Iowa, but Romney has made up for it among female voters in swing states. The Romney camp shouldn’t get too excited just yet; Obama is exceeding his early voting targets that give him actual votes in Arizona, Ohio and other places.
