The principles of Conservatism aren’t constantly moving to the left. All of the candidates, except Thompson and Hunter are moving to the left.
The MSM is a living, breathing force that is pulling/skewing everything to the left. McCain will be touted as a conservative by the MSM. In reality, McCain is probably leaning a little on the liberal side of the Liberal/Conservative meter.
On a scale of 0 to 100, with 0 being ultra left and 100 being ultra conservative, here are where the candidates actually rate:
Clinton = 5
Obama = 8
Edwards = 10
McCain = 40
Giulinai = 40
Romney = 45
Huckabee = 45
Thompson = 75
Hunter = 85
I agree with your rankings . . . including the shocking fact for Freepers that Huckabee is the most conservative candidate still in the race. Except . . . I think Obama is just as liberal as Hillary.
I generally agree with your scale, but I think Fred gets too much credit for being extremely conservative. Voting against tort reform is a major blemish. My ratings would be:
Obama = 2
Clinton = 9
Edwards = 10
McCain = 55
Giulinai = 58
Romney = 62
Huckabee = 64
Thompson = 67
Hunter = 95
