Bradley Effect Expanded?

Can We Talk?

Limbaugh stated that if Obama doesn't come out of his convention with at least a 15 point lead over McCain, he's toast.  That would be true of any democrat, in any year (democrats always get puffed polls after conventions, look it up), but because of the Bradley Effect is especially true of Obama.  So here's the question: If McCain chooses Romney, will his Mormon religion trigger a similar effect among evangelical Christians, and thus even the playing field?  That little weasel Huckabee certainly played it for all it was worth during the primaries.
