I'm inclined to believe (at least partially) Clint Eastwood when he says that his surreal performance at the Republican Convention was mostly him fucking around at the expense of both the President and the people "dumb enough" to invite him to their convention. Okay, fine.
That said, his "Invisible Obama" sketch has, intentionally or not, given Republicans a new racist effigy it can use to get it's point across i.e. rage at the Scary Black Man in the White House and long, long, long overdue un-bleaching of America he represents to them.
And, sad to say... yeah, this shit does probably get to be part of Eastwood's legacy now - live by The Right, fall by The Right.
