CNN says 47-45 for the Democrats in their new poll of likely voters:

Republicans led by 4 points in their previous poll.
Hardly consistant with a so-called "Republican-wave" building, as some say ...
At this point in 2010, all polls showed a 5-10% GOP lead.
Not only that, but Rasmussen's latest generic ballot from yesterday showed Democrats ahead by 1% among likely voters.
Maybe it's the massive requests of in mail ballots all across the country by Democratic voters that is finally starting to make its impact.
Taken together, CNN and Rasmussen polled 4,200 likely voters, so it doesn't have to be a statistical fluke either.
Also, Obama's disapproval numbers have been massively scaled back in almost every poll during the past week. He's in the single digits everywhere now, while most pollsters had him in the double digits before that.
