I like that definition of "rule by Democrats." That's definitely what the Democrats want, a one party state, like the Nazis had and the Communists have. I notice that the Democrats always like to state that the U.S. is a "democracy," while Republicans are often stressing that, no, the U.S. is a republic. They're both wrong.

If you pay close attention, you'll notice that Democrats usually say we live in a "Democracy" (obviously there's no way to tell if you're hearing them talk.), and with the definition I gave, they are correct.
As far as I can tell, this is the only way to make sense of so many seemingly hypocritical statements made by Democrats.
