Only 51%? That should be higher.
I’m surprised that 26% think that Giuliani’s conservative (they must be Sean Hannity listeners) and I’m amused by the fact that only 30% thought McCain was. This is what you get for ticking off the conservative base:

During Fred Thompson’s first month as a formal candidate for the Republican Presidential Nomination, Republican voters continue to see him as the most conservative candidate in the field. Fifty-one percent (51%) of Republican voters now see the former Tennessee Senator as politically conservative. That’s up from 48% a month ago.
Perceptions of Mitt Romney have moved in the opposite direction. Thirty-six percent (36%) now see him as politically conservative. That’s down from 42% a month ago and little changed from two months ago.
Just 30% of Republican voters see John McCain as politically conservative, down from 33% a month ago. Twenty-six percent (26%) hold that view of Giuliani, little changed over the past month.
