Perhaps, that's what elections are about. If he enters and Republican's don't vote for him because of his "negatives", he loses. Same for the general.
Based on negatives, Hillary doesn't stand a chance, it's Obama in a landslide followed by Edwards. And Giuliani is the only Republican with a remote chance of beating Obama, particularly Obama/Edwards. Things will change.
I think Mitt is the only canndidate with the appeal to beat either Hillary or Obama.
Yes, and the D's will be stupid if they nominate her. Let's not follow them in their stupidity to nominate someone on our side with even HIGHER negatives. (Hillary's are 48% last time I saw, and as it was pointed out, Newt's are in the 60's.)
