If you’ve been watching cable news lately — you poor soul — you may be aware that four Republican lawmakers are promoting a new right-wing-media-inspired witch hunt.

No, we’re not talking about ACORN-bashing or “czar” paranoia here. Them’s old news, partner. But did … did …did you know that Muslim spies are infiltrating Congress?!

So says loon fringer David Gaubatz, co-author of Muslim Mafia: Inside the Secret Underworld That’s Conspiring to Islamize America, published by World Net Daily Books.

Politico has more on the “controversy” here.
