Nonsense, Palin would have defeated Obama in 2008 or 2012 as top of the ticket.
Romney was a party destroying disaster in 2012, and that should have been clear from his dismal failure as a governor who left office with 34% approval, and then entering 2008 as the self funding, establishment, 800 pound gorilla with a massive organization and the big donors, who then lost to two unfunded mediocrities, with no organizations or staffs.
I would vote for Palin if she ran. But you need to quit fooling yourself. The GOP leadership will do everything in their power to prevent Palin from being the nominee. And as popular as she is, we need the ENTIRE GOP working together to defeat the Dems.
