i hope its simply her being polite. Trump is a liberal
So is most of the GOP field. I still think that Trump is Palin's best chance of sinking Romney in the early primaries. Romney can drop out again after he gets trounced multiple times, and the field becomes clearer for Palin.
Without Trump, I'm not sure how she stops Romney. He's been campaigning for 6 years, has a solid on the ground effort in the early primary states, and a whole lot of people who've voted for him before. Not to mention the MSN recognizes how massive a threat Trump is to The Zero, and how much of a financial drain it would be on the Democrats with Trump just as a possibility (putting New York in play.)
Honestly, it really feels like Palin gathered up all those GOP whisperers and ejected them a couple weeks ago, then sat down at the kitchen table and plotted out how to win the election.
