Actually, I don't believe the above statement is generally true (though it may apply to some), and thus I don't make that argument. Btw, in my opinion the best explanation for conservative support of Guilianni is they are running scared. When people are running scared, it hampers their ability to make good decisions.
Let me just say, further to your post, that my support for Rudy isn't because I'm running scared.
I lived in CT and my husband and in the 80's my husband and I used to go into NYC several times a month. We ultimately stopped because the crime was so rampant we no longer felt safe. Rudy turned that around and we resumed visiting again.
I've had my eye on him since the early 90's, maybe since the late 80's. I've always thought he was too big to be just mayor, even though NYC's economy is bigger than all but 5-6 states.
