" The great DNC slime machine", pdq? I fail to see how a truthful, dispassionate recounting is sliming them.
Giuliani is not the GOP's most respected candidate, of course. He has a life history and views that most of the party will not likely be able to swallow.
On the other hand, the religious right fell in love with Ronnie, notwithstanding his divorced status. So maybe.
Romney has other problems. Perhaps you are not aware of how the religous right feels about the heretical Mormon church.
