Jonathan Cohn hasn't caught the Pawlenty bug:
If you want to put it investment terms, Romney’s problems are priced into his stock. Shares for the other candidates are probably trading too high. Keep in mind that Romney has been through a presidential campaign before. He knows how to deal with attacks–and how to attack back. Plus he has a huge fundraising advantage.
I suspect Jon is right. And it may be that Obama-hatred outweighs Romney-Skepticism among the Christianists and Tea Partiers. But the field is still open – and the Bachmann-Palin bus has yet to leave the station.
