Ping sorta.
I think I have an idea what we are seeing in the numbers. It's something he says in the article about the small business owners: in 08, it wasn't just that people didn't like McCain. They were so ready for a change from Bush/2006-2008 policies that they were willing to vote for Zero regardless of his background, policies, or ideas.
I think the same is now true, to a lesser degree, with Romney. It isn't that people like or don't like his policies or ideas. THEY DON'T CARE anymore than in 08. They want Zero out, not Romney in!
What tells me this is the case is the lack of Romney signs and stickers---still far more than Obama this time around---yet there is a high level of local activity in phone banks (setting records in our are and, as I have heard, in FL) and walkers. These aren't "pro-Romney" people but anti-Obama.
Even the job approval, I think, doesn't reflect this in polls. I wonder if you had, without mentioning Romney, a poll that said something like "Do you think Obama deserves another 4years," his "yes" numbers would be in the high 30s.
