I don’t believe he embraced either Palin or the Tea Party during his campaign
Perhaps he did not embrace them, but according to the TEA Party Express, they embraced him to the tune of $350,000.
From a TPX e-mail:
We've spent over $500,000 against Sen. Majority Leader, are spending more than $250,000 to Defeat Bart Stupak, and spent around $350,000 to help elect Scott Brown to the U.S. Senate.
