There is actually very little that's conservative about Giuliani, other than his law-enforcement record.  Yes, he made the trains run on time, but some of his supporters are willing to write-off large segments of the conservative coalition, which are not found in New York City or the District of Columbia, with their wave-of-the-hand dismissal of serious issues Giuliani will have to overcome.  But please, spare us the fiction that he's some great conservative.  If I vote for him, it will be because all the Democrats are so deplorable, not because of his embrace of radical environmentalism, open borders, gun control, abortion, and the rest of it.  And, yes, he's leading in national popular polls.  But that's not how nominees are selected, is it.  You have to battle in each state, and the process is full of unexpected political dangers.  So, I'd say it's a little early to declare a winner.  It's painful to watch people pretend that Giuliani is something he is not and never has been.
