Former Bush strategist Matthew Dowd may have nailed down that honor today in the pages of the WashPost.
Behold this car wreck of a nut graph:
Yet while the conventional wisdom has it that Palin is too badly damaged to make a serious run in 2012 -- and I agree that her success is not probable -- it is definitely a possibility that Palin could be elected president of the United States.
Dowd doesn't think Palin can become president (it's “not probable”), but there's “definitely a possibility” that Palin could become president.
Honestly, what more is there to say?
UPDATED: As a bonus, Dowd lied about this:
Polls show that Palin's favorability numbers are a mirror image of those of Obama.
