Sarah says it, as usual straightforwardly "I am not convinced." Since Romney generally runs about 30% vote support, and generally is doing worse in support compared to the same primary states he ran in 2008, neither are about 70% of the rank and file.
Here is Romney's (declining) 30%
Palin is absolutely right that the primary and vetting and candidate position process must continue. Ideally, for me, right till Tampa where none of the current candidates have a majority of delegates (although I would be happy with Newt as the nominee) and the convention turned to her or someone else who is a genuine conservative.
Unlike Sarah I am not so sanguine as to believe Romney will ever be identified as a true conservative, as she hinted at yesterday at CPAC and, even if she endorses him if he is the nominee, will not vote for him.
