Does McCain vote identical to President Bush?

The following study is sort of interesting. I have been thinking about the newest talking point of McCain voting with Bush 90% of the time. Actually what is being used is that McCain voted with the party 88.6 % of the time. This study shows that in reality McCain does differ from President Bush. What isnt being told is that Barack Hussein Obama has voted party line 96% of the time. His buddy Joe Biden 96.6% of the time. Wonder how long thsi tactic will be used by the Dems
