Well that's no surprise. Lieberman is very liberal on almost every issue just like McCain is conservative on most issues. They both however love to show their "bi-partisanship" and that they have "moderate views", therefore they are hated by their own parties and loved by the other party. However if you look at f.ex. the ACU Ratings you'll see the truth.
Lifetime ratings:
Joseph Liebermann 17
Compare this with:
Tom Carper 18
Harry Reid 21
Sheets 30
and many other Democrats who have higher ACU rating than him. Yet you'd never expect Dingy Harry to vote for Alito. OTOH:
John McCain 83
Compare this to:
Judd Gregg 79
John Warner 81
and some REAL RINOs:
Magic Bullet 44
Lincoln Chaffee 41.
Well yes, and I agree with you on Lieberman. But McCain having an 83 ACU rating in itself doesn't present the whole picture. Judas had a 99 out of 100 Jesus rating...
