I got a pretty good source for that one.
Whoops, you got me there - I was working off of a premlimary version of that page. My apologies for the error.
I sure wish I could find a reference to Obama's big lead in early voting - everything I've found shows a slim lead, but nothing like the large margins he had in 2008. If Romney can limit Obama's lead in early voting to less than 100,000 or so, he'll win.
