Help wanted from you, my incredibly knowledgeable readers

One of the points my liberal friend has made in the last few talks we’ve had is that the Tea Party candidates are dangerous nuts (witness Christine O’Donnell’s flirtation with witchcraft when she was 16).  He claims that the Democrat candidates and politicians are models of normalcy.  I was wondering if you could help me put together a sourced list of insane, intemperate, bizarre Democrats, both candidates and elected politicians.  I’ll get it started:

Alan Grayson (D-Fla):  “The Republican health care plan is this: ‘Don’t get sick, and if you do get sick, die quickly.'”  “I apologize to the dead and their families that we haven’t voted sooner to end this holocaust in America.”

Charlie Wilson (D-Ohio):  Brutal wife beater.

Bob Etheridge (D-NC):  Assaulter of citizens.

Pete Stark (D-CA):  Wouldn’t dignify conservatives by peeing on them.

More, please?
