The concern I’d think would be that her primary support would harm the Pubbie position in the general. Schiff needs a hail mary to have a chance, and I suppose that would be Palin.
Yup.
A Palin endorsement would help win the nomination, but in the fall it could hurt with those who dislike Palin.
Because it’s a risky move, a Republican front runner in New England might not want the endorseement. Schiff, who is likely behind in the polls at this time, might want to try it, but I’m not sure it’s quite a hail mary pass.
