Why Is Romney Slipping In The Polls?

John Cole gives a hypothesisfor  why Romney has dropped in the polls:

BTW- notice that it never occurs to Caddell that the reason Romney is failing is because his ideas are awful, the Republicans are insane and dangerous and represent about, well, 27% of America, and he is out of touch with America. No, no, no… It’s just bad messaging. That’s like saying rectal cancer is unpopular only because it has a shitty logo and the jingle sucks.

I really do think that some fence sitters tuned into the Republican National Convention, listened to those nuts talk about a Barack Obama who doesn't exist, wondered how the GOP thought  slashing federal spending and handing out even more tax cuts would balance the budget and promote economic growth, and they decided they didn't want to board that crazy train.  Then tuning into Bill Clinton explaining in plain English that Republicans are idiots sealed the deal.  The polls will probably get closer down the stretch, but widespread exposure to Republican "ideas" put them pretty well behind.
