There were two key moments for me when Sarah Palin blew it badly. One was substantive, one was symbolic. The substantive was her bizarre statement about being happy that Dick Cheney had expanded the powers of the vice-presidency, and wanting to expand the powers more. I think that’s what she said, it was one of many moments I didn’t entirely understand her point, but I got her overall meaning. Biden came back with a decisive: “Vice President Cheney has been the most dangerous vice president in American history,” and he defended the existing limits on vice-presidential power. Point: Biden. Big time.
