Carville is waiting in the shadows for the neverendingcouple to emerge from lalaland. They will and when Hillary takes stage, Snake Eyes will be there. I believe Carville detests this current White House resident. If not, he certainly has a funny way of answering those who disagree with his statements.
I wouldn’t be so sure, since Hillary clearly stated she’s not running (for now).
I suspect it is the same act that Jesse Jackson pulled, whispering about Obama and his nuts, etc. As it turned out, it is all for show, and to generate more publicity for candidate Obama at that time.
