With DeMint, Pence, Christie and Thune gone, and the fact only Romney and Huckabee are competitive (and barely, at that) in a hypothetical general tells me the GOP has a horrendously weak field.
Good people see what happened to Palin. They're simply not willing to subject themselves and their families to the political meatgrinder.
This is a great source of comfort to me, as I watch the usual RINO egomaniacs parade about making their big inferences about throwing in their hat. Perhaps there is a true conservative in the wings who we haven't thought of yet.
