Like most leftists and the GOP, they will say anything if they can get it to end in "Keep Mrs. Palin out."
When Governor Palin gets in, Michelle will stay for a while (to save face) then drop out and support Palin.
Would she support Palin when it’s time for her to drop out? Hmm...I suppose my bet is yes, I do believe she is ultimately a principled person—but you just never know.
I agree with everything you said with exception of MB supporting Palin.
Yes she will finally endorse Palin in the general, but only because she will have no choice, but I do not see her supporting Sarah in the primaries at all
