» It’s the largest lead either candidate has held over one another since The Washington Post/ABC News started polling Romney-Obama match-ups in April of last year. It’s also a huge reversal from just a month ago, when Romney led Obama by one. Why the change? Well, it could be the (slowly) improving economy, or the insanity of the Republican primary taking its toll on all the Republicans, or Romney saying that he’s “not concerned about the very poor” on CNN last week. Or maybe, people are just fickle, and Romney will be twelve points ahead of Obama next week.
