Those town halls are getting uglier.

A dozen gun-toting paranoid guys walking around at Obama’s town hall in Arizona yesterday, some of them with ties to the violent Viper Militia.

In the video above, Barney Frank takes a question from some woman who’s comparing Obama to a Nazi and tells her she’s talking “vile, con­temptible nonsense”.

I hope it’s not going to escalate into outright violence.
