Rasmussen Tracking Poll for 5/31

Romney 46%, Obama 45%. Perhaps more telling: for the first time this year, Romney leads in all four of the large swing states, Ohio, Florida, North Carolina and Virginia.

Rasmussen, of course, surveys likely voters. Interestingly, the two most recent Gallup polls of registered voters shows a similar result: Romney 46%, Obama 46%. While history would seem to be marginally on the President's side, this is going to be a very competitive election, and a very close one. And it's anybody's to win.

Except Gary Johnson's, of course! ;)
