Tancredo: Most Conservative Running for President
The American Conservative Union only rates members of Congress (Representatives and Senators), and among those Tancredo has the highest ACU rating -- 97.8 ACU Rating. The governors in the game -- Thompson, Huckabee, and Romney -- and Mayor Giuliani have (or had) liberal stances on some issues. So, if they were given one by the ACU, no reason to think their conservative ranking would outrank Tancredo.
A fact Tancredo is very proud of.
