Well, among other things...
Well, yes, I have other names for them too, but not as polite. "idiots, morons, dumb-asses, and really stupid dumb-asses" come to mind. But as far as I can tell, "Republican" encompasses all those.
And I say that recognizing that some Democrats are "idiots, morons, dumb-asses, and really stupid dumb-asses" as well... It is just that the "idiots, morons, dumb-asses, and really stupid dumb-asses" Republicans seem to outnumber the Democratic ones 3-1. And if any Republican out there wants to get competitive, OK 4-1. You win...
