Tina Fey channels Palin. It's so close it's kind of freaky.
The problem for Fey is that this is not really a parody because you can't actually parody her.
Here's a quote from Palin's actual endorsement:
"You quit footin' the bill for these nations who are oil-rich, we're payin' for some of their "squirm-ishes" that have been goin' on for centuries where they're fightin' each other, callin' Allah Akbar, callin' jihad on each other's heads forever and ever. Like I said before, let 'em duke it out and let Allah sort if out!"
