How will Sarah Palin's successor play on SNL?

Alexandra Petri observes in "Michele Bachmann, the GOP debate and the SNL Palin factor," in part:

... Caricature tells more than portraiture about the features of a face. Look at Tina Fey’s star-making turn as Sarah Palin on “SNL.” Ideal meat for parody is someone who is funny without knowing or noticing why. That was Palin in a nutshell. Her whole selling point was not what she said but how she said it. She seldom said anything at all, so this was a good side to emphasize. You could fit most of her theses into the navel of a gnat and still have room for six caraway seeds and the social value of the exercise of looking through her e-mails. Helicopters! Wolves! Russia! She was as funny as you could be without being an actual joke. It just took Fey’s knowing delivery to push her over the edge. ...

... But what about Bachmann, whose star-making turn as The Lady With 23, Count ‘Em, 23 Foster Kids and Who’s Gonna Make Barack Obama A One-Term President, has left everyone wondering how it will play on “SNL”? ...

Will "SNL" ever be as much fun again?
