Don't hold your breath on that, I'd be willing to bet money that Fey despises Sarah. She really didn't want to come back to SNL, but Lorne Michaels persuaded her with a bucketfull of money, and the chance to do something to bury the McCain-Palin ticket by ridiculing it.
The best way to deal with that ridicule is to roll with it, the American public appreciates a candidate who's willing to laugh at themselves. As for the View, that coven would be a dangerous place to be, but if you won't go into that lion's den, how can you say you'd go into the presidency?
The base has been bucked up by the unfair criticism that Sarah's taken from the insects at the margins of the media. Perhaps the bonbon eating crowd who have time to watch daytime TV would benefit from seeing it, as well.
Well then, you'd win the hand. In spite of the fact that the impersonation of Palin has put Fey high up on the map, she is on record as saying that she wants a reason to NEVER have to do that again after the election. Nuff said.
It is my opinion that the only thing Tina Fey will be remembered for by history is her impersonation of the first female Vice President of the United States.
