Although Bush's numbers are low (that's a fact), we must remember that this, like the Fox poll, is a poll of "adults," not "registered to vote," "likely to vote" or "most likely to vote." And of those "adults" CNN polls 8-9% more dems than Repubs, and a larger than normal group of "independents." If Scott Rasmussen were to poll individuals "likely to vote" using his proven methodology Bush would probably come in around 45% or so. Not great, but certainly not 32%.
see my above post, Scott has him at 40% today..
