THIS.
Right or wrong, Cheney will be tainted by Bush for the rest of his natural life, regardless of anything else he ever says or does. He should never be floated as a serious candidate for that reason alone.
Cheney is dead because as we saw last year...anyone with health problems in the past or a bit too over the hill is a liability. Whether you like it or not the age thing was just as much an issue with McCain as was Obama being black or half-black.
But for some reason, Libs dislike Cheney more than Bush. So yes Cheney will be tarnished for being in that administration.
