Move over, Palin: Tina Fey has enough material. Now McCain is trying to get in on the act by taking time out of his hectic last weekend of campaigning in the swing states to appear on Saturday Night Live. He will appear alongside Ben Affleck, a devoted and humorless Obama supporter, and hopes to win some belated support among the younger, hipper, funnier crowd. An uphill struggle, you might think. But the last time he appeared he showed exemplary self-knowledge and humility, addressing his audience with, “I ask you, what should we be looking for in our next president? Certainly, someone who is very, very, very old.” Maybe he will have the last laugh after all.
