Yes the GOP has no one else to turn to other than the lunatic birthers. Tonight Louisiana Rep. Charles Boustany will be delivering the rebuttal, and here you can see him in his lunatic crazy fashion.
Adding – the GOP had one other rebuttal to President Obama addressing a joint session of Congress. Interesting enough it was another politician from Louisiana, who is also on the lunatic fringe (hint – his initials are Bobby Jindhal). I guess learning lessons is really rough from the Republicans.
