So I invite readers now to try to out-parody the Palin criticisms ahead of time. I'll give it a shot first:
Palin's performance tonight marked the low-point in modern vice presidential history. By comparison, she made Dan Quayle look positively Solomonic. This red-neck moron with her hackneyed down-home manner was an embarrassment to the Republican party but most crucially to John McCain. No candidate for president ever dared to place someone as manifestly stupid and unqualified so close to the Oval Office. The fact that McCain chose this woman is, alone, reason enough for America to reject him root and branch.
I'm certain you can do better.
