You are absolutely correct. A Guiliani candidacy will result in a Democrat president. What do you think about Governor Sanford? He's my man at this point.
Sanford seems like he would make a good candidate, but not sure if he can get enough traction to win the nomination. Pawlenty is another good choice.
However you are delusional if you think a Giuliani who survived the primaries wouldn't win in the general. Only Colin Powell might draw a bigger general vote, but he would have an even tougher time winning in the primaries.
