This is extremely well done. Congrats!
The abuse you are taking for Romney being so high is a bit unfair. Scoring Romney is difficult because he comes across as so darn insincere and he doesn’t SEEM like a Conservative because he parses his positions like a Liberal.
Personally, I think you did a great service for the Posters of the Free Republic with this “rating system” of the candidates.
Romney was a tough one. On several issues he talks like a conservative, Gay Rights, Abortion, Guns, but his record in MA on these issues is certainly not conservative.
However, in order to be a SUCCESSFUL politician, you must tailor your message to your constituency to a degree, I had to try to judge if some of his more liberal policies were necessary in Boston for overall success there but would be less of a factor in Washington. Never-the-less, because of his past, I did grade him lower on several issues in which he now says he is strongly conservative.
