Anonymous Liberal doesn't think Palin has a shot at '12:

I'm not at all convinced. While there's little doubt that Palin is very popular in certain GOP circles, her fan club is artificially inflated right now and her pool of conservative detractors is artificially small. There are a number of conservatives who are holding their tongues right now because they don't want to further damage John McCain's chances. If McCain loses, the GOP will quickly descend into recriminations mode. Many conservatives who have been holding back thus far will unload their frustrations about Palin.

Ross imagines that she could win the primary but not the White House. I think she's a Wonderbread loaf, now very well-toasted.
