RYAN SAGER: “The parallels between 1994 and 2006 keep piling up. Republican denials that there could even possibly be a problem might just be the next piece of the puzzle. . . . Chances are, though, that the Republicans will muddle through. But, if they’re paying attention, they also know that their continued success at this point is owed entirely to their adversaries’ inexplicable incompetence. Bush, in this second term, is weak; but Nancy Pelosi and Harry Reid are like lactose-intolerant kittens.”
