Obama or Clinton?

I have a hard time deciding if Obama is more unprincipled than either of the Clintons.  But no, I think that Obama is more unprincipled: I think that the Clinton don't have a set of core beliefs. They buy and sell. I think that Obama, on the other hand, has a set of beliefs (and they were never leftists ever) but that he is willing to sacrifice them for the pursuit of minimal political power.
