I have a third problem with it: there’s no way to rate McCain higher than #1. ;)
The fact that all three front runners for the Republican nomination last time (McCain, Hucabee, & Romney) made the list shows there is a problem with the Republican nominating process.
All three belonged on the list (imho), because none has a track record of enacting conservative ideas when they held office. In fact, when they held office, they all three enacted liberal ideas.
Going on what they actually did in office (not what they say) you would rate them:
Huckabee - least liberal
McCain
Romney - most liberal
Words mean nothing. What they do in office is all that counts.
Yep, but not all surveys offer precise metrics so it'll have to do.
