Of the 9 votes he made, he voted sideways on two. And look at the two he was bad on:
[-] 07. Stem Cell Research S5 (Roll Call 127).
[-] 09. Immigration Overhaul—Cloture S 1348 (Roll Call 206).
If one counts his missed votes against him, He voted ACU Conservative only 7 of 25 times.
That would be a rating of only 28%.
Here's his bad votes in 2006:
[-] 04. Tax Cut Rules S Con Res 83 (Roll Call 38)
