This clip has been making the rounds today, in which Gov. Mark Sanford (R-SC) does a total faceplant trying to articulate any contrast between McCain and Bush on the economy. This is one of the worst appearances by a high-profile surrogate you'll ever see, and it highlights the severe message difficulty McCain's campaign is having on the economy. Look:

Brutal.

(Also, as Taegan Goddard notes -- we can probably strike Mark Sanford off McCain's VP list.)
