I find Rubio to be a particularly pathetic creature
A Teahadist darling until he dared to betray them by supporting immigration reform. With his poll numbers tanking he has decided his dreams of being president can only be saved by pretending to be a crazy who wants to shut down the government. Too late though, his support was always soft with southern whites and his fall from grace is irreparable.
I agree Bush and Christie are nothing like the other clowns. We'll see how far they get.
