Willie is good for a rant. His might even be the proper tactic when dealing with the Clintons, but going after Obama requires different tactics.
Barak didn't name himself. If he had changed his name to it, then it might be a valid point. Now pointing out his socialist policies is more than fair game and should have been the focus instead of repeating Barak Hussein Obama. Even pointing out his connections to the Daley Crimo-political family I think is fair game. If Obama has had close relations to Saudi money I would go after that. But he had no control over what he was named. Going after than will just get the press to jump on McCain to the exclusion of anything relevant he had to say.
Would Iraqi $ (as in Saddam Hussein) do?
