Sarahcuda knows, from her brush with Barry on the campaign trail, that he is vulnerable on matters that demand a visceral and muscular response rather than a logical and book-learned one. Mr. Obama was charming and informed at his town hall in Montana on Friday, but he’s going to need some sustained passion, a clear plan and a narrative as gripping as Palin’s I-see-dead-people scenario.

She has successfully caricatured the White House health care effort, making it sound like the plot of the 1976 sci-fi movie “Logan’s Run,” about a post-apocalyptic society with limited resources where you can live only until age 30, when you must take part in an extermination ceremony called “Carousel” or flee the city.

Painting the Giacometti-esque Emanuel as a creepy Dr. Death, Palin attacked him on her Facebook page a week ago, complaining that his “Orwellian thinking” could lead to a “death panel” with bureaucrats deciding whether to pull the plug on less hardy Americans.

Never mind that Palin herself had endorsed some of the same end-of-life counseling she now depicts as putting Grandma down.
