Good question. See here for an answer:

American Conservative Union Ratings:
| Senator | 2005 Rating | 2006 Rating | Lifetime Rating |
|---|---|---|---|
| McCain | 80 | 65 | 82.3 |
| Clinton | 12 | 8 | 9.0 |
| Obama | 8 | 8 | 8.0 |
Is McCain a perfect conservative? No. Is he far more conservative than either of the two rats who will be sitting in the White House if we persist in this self destructive tantrum? Hell, yes.
Well put.
I saw nothing on that chart to indicate which votes were close.
