I could actually vote for the guy if he is the nominee. He was a great mayor (at least his first term. He had the normal 2nd term problem that almost all Republicans do). If I thought he actually bought into Forbes's worldview of a flat tax, privatising social security, at least holding government spending to the level of inflation, and he really, really meant it and would fight for and champion it, I might even vote for him in the primary.
I have told myself that I could never in my life vote for an abortionist or gun grabber, but the GOP has so completely screwed up this country and destroyed conservatism in the last 6 years with Medicare, all the other spending, etc, that I could go for a guy who promises neutrality on the abortion and gun issues if he would be a real supply sider.
Unfortunetly, as soon as Giuliani said some nice things about the flat tax, he backed off of them.
I too will be interested to see how he fleshes his position on the flat tax out during the debates. His statements so far have been sketchy and seemed on the fly - or at least press coverage of them read that way - it is incumbent on him and his team to nail that down. I am hoping the flat tax is part of his platform.
