Take a look at the current numbers:
Latest Swing State Polls
Here are the latest polls from the battleground states, updated as needed:
Colorado: Obama 49%, Romney 48% (Rasmussen)
Iowa: Obama 49%, Romney 47% (Rasmussen)
Michigan: Obama 49%, Romney 46% (Foster McCollum)
Michigan: Obama 48%, Romney 45% (EPIC-MRA)
Pennsylvania: Obama 47%, Romney 45% (Susquehanna)
Looks like Obama is retaking the lead he had yesterday. Even two of the Rasmussen polls, which are the most conservative of all the polling organizations, are putting Obama back into the lead.
