Hmmm...Libbie villain.
@robosmith would be the obvious choice but...is a simpleton capable of being a real villain?
There's @BeaverFever. But he's become rather irregular here.
Ya know...I'm gonna go with @Michael Hardner. Mike is a true villain because he professes to be conservative, yet consistently sides with the Libbies. To me, that's dirty pool.
HOWEVER...I would like to give honourable mention to @myata. Yes, his brains are a plate of scrambled eggs but...he tries to damn hard.
