Gov. Palin tonight will reveal on Greta Van Susteren's On the Record which declared candidate she believes has the best chance of beating Obama in 2012, according to promotional language on Fox News' home page and in a promo video.
If the foregoing is true, we can reasonably conclude that all reconsideration, "earthquake" and other such efforts should cease. Further, this pick may or may not constitute an official Palin endorsement of a declared candidate.
