I was "pulling percentages out of the air" when I suggested that Rudy Giuliani was a conservative on no more than 15% of the issues.
The 20% has some validity to it. If you go back through his public record and tally his positions on any number of issues, you'll probably find that he'd garner an ACU rating of no more than 20-25 if he had been a member of Congress.
You didn't name the issues, so I have no way of verifying what you tell me. Does it go like this?
War on Terror
Limited Government
Abortion in the third week
Abortion in the fourth week

Abortion in the 20th week
Embryonic stem cell research
Etc., etc.
