Sarah Palin's recent high-profile appearances have fired up her critics and inspired palm-reader jokes. But Washington Post columnist David Broder counsels the political establishment to "take Sarah Palin seriously," seeing in her National Tea Party Convention speech and Fox News interview "a public figure at the top of her game — a politician who knows who she is and how to sell herself, even with notes on her palm."Broder expands on the point. "There are times when the American people are looking for something more: for an Eisenhower, who liberated Europe; an FDR or a Kennedy or a Bush, all unashamed aristocrats; or an Obama, with eloquence and brains. But in the present mood of the country, Palin is by all odds a threat to the more uptight Republican aspirants such as Mitt Romney and Tim Pawlenty — and potentially, to Obama as well."
