Haley Barbour declared today he won't run for president. Weigel says this "frees up a ton of money for [Barbour's] friend Mitch Daniels":
That's not to say that no Barbour = more Daniels. It's just to say that Daniels, who'd worked with Barbour during the Reagan administration, was extremely unlikely to run against his old friend. And now Daniels has one less excuse. He still has plenty of them.
Frum, on the other hand, thinks Barbour not running helps Romney. Earlier thoughts on Barbour here.
