Caling Dems 'Dims' has an appropriate origin Clockwork Orange character named Dim is described quite a lot like the mindless gnomes rallying behind the democratic party.  Calling them Dims is very appropriate. Dim is unintelligent and child-like, but highly aggressive. He is as violent as Alex and the other Droogs, but is a stronger fighting, being described by Alex in the fight with Billyboy as "worth three of the others in sheer madness and dirty fighting." He rarely has his own ideas mainly following others; first Alex then after the fallout Georgie.  http://a-clockwork-orange.wikia.com/wiki/Dim
