Liberals have been making jokes for the past year about the otherworldy "Can You Top This?" game being played by Republican presidential candidates, each one offering up a more buffoonish idea than the next in a vain attempt to prove that they're the purist conservative in the pack. Well, now Herman Cain has trumped them all: his 9-9-9 plan is too goofy even for the modern party to embrace, but it obeys conservative orthodoxy to a tee. So how do you convince all those people you've been selling conservative orthodoxy to that this, finally, is something that goes too far? Isn't that the kind of thing a liberal would say?
