I've been around long enough to have seen the race card played--most famously by Clarence Thomas of "high-tech lynching" fame.  Can Bill Clinton (sorry buddy, you are every bit as white as I am) say Obama has done the following?

play the race card, v • political tactic to appeal to racist motives in the electorate. Alternatively; political tactic to appeal to non-racist motives in the electorate by accusing an opponent of appealing to racist motives. 

Furthermore,  can Bill make the claim that he is a victim of racism?  Maybe so if you have enjoyed being called "the first Black president" for years and never bothered to remind folks you are white.
