Roughly half the country votes Democrat, and why would they want a change?
Typical Democrats (the condom-throwers, abortion enthusiasts, gold-chained union thugs, ACLU athiests, welfare grandmothers, Boy Scout hating lesbians, hand-wringing college professors, and the rest of the parasites, losers, goofballs, and bitter malcontents who comprise the Democrat party base) have never cared much about traits like upstanding moral values, honesty, or experience in their candidates.
For them, its all about how much free stuff they think their politicians can confiscate from hard-working, taxpaying, traditional American families (the Republican base) and hand over to them in exchange for their votes.
And so, the only way Democrats will “throw the bums out” is if somebody even worse comes along to replace them.
Truer words were never spoken [re: the Democratic base’s motivation for voting]. I have Dem friends who hate congress, but only because they’re not taking more from “the rich” and giving it to the Dem base. These people are not going to throw the engineers of the gravy train out any time soon.
