This week, Christine O'Donnell appeared on a national news show to announce that she wouldn't be appearing on any more national news shows. Sarah Palin surprised no one by telling Fox News she would run for president in 2012 "if nobody else wanted to step up." (Her problem is that even her base doesn't see her as Oval Office material: she came in fifth in the Values Voter Summit straw poll.) Also not surprising anyone: Senate Democrats, who, fearing GOP attack ads, decided to put off a vote on extending tax cuts until after the midterms. In better economic news, Larry Summers announced he'll be stepping down as director of the White House National Economic Council. I've always felt Summers was the wrong man for these troubled times -- a brilliant mind with toxic ideas.
