The only thing that keeps Bush "relevant" is that he is the go-to defense for Obama's failures; "Well, he did it too."
It's a juvenile defense without substance, which calls for a parental response: "If everyone jumped off a bridge would you do it too?"
But like my Mom used to say, "I don't care who started it, I'm going to finish it" (usually followed by a good ass-whooping with a shoe). America needs to get its apron on and "finish it" too. If the Republicans couldn't do it, and the Democrats aren't doing it... then that's probably why a third party is emerging... to get it done.
