Man, this guy is a cornucopia of dumbstupid. Here's Rand Paul using the phrase "welfare queen":
“We as Republicans need to realize that you can’t just cut off the welfare queen and balance the budget,” says Rand Paul, a Senate candidate in Kentucky, who has some extreme views on other issues but is evidently pro-arithmetic. “The only way you’ll ever get close to balancing the budget is if you look at the entire budget.”
He obviously missed the race-baiting class when they talked about not using actual racist terms. You don't say "welfare queens," you merely imply it by talking about wealth redistribution by the black president. Idiot.
