Obama's new ad attacking Palin provides an opportunity for the McCain-Palin campaign. Palin should hold a press conference today to respond, and do TV, radio and print interviews. In them, she should take on the Obama campaign on economic policy--the topic on which the Obama ad ridicules Palin's alleged unpreparedness. In fact, economics--taxes and energy in particular--is an area in which Palin's been a strong spokesman for the McCain campaign. So put her out there. And let her accept the Sunday shows--and challenge Biden to debate economic policy with her on the Sunday shows. A Palin press conference and interviews today would also 1) step on Obama's prime time speech tonight, and 2) put to rest rumors of tension within the McCain-Palin campaign, and show that everyone was doing their best to elect the ticket, rather than focusing on defending individual staffers' reputations or past decisions. The tracking polls suggest McCain has an outside chance to win. The campaign should go for it.
