Donald Trump is back. Again.
Will he run? Or will be endorse? And if he endorses, who would he pick? Mr. Trump could throw his weight behind an insurgent — Newt Gingrich or Rick Santorum. Or he could go with the establishment pick — Mitt Romney. Given his back-and-forth with Ron Paul, it seems unlikely he’d back the Texas congressman. Or maybe he, too, will sound a Herman Cain-esque endorsement of “the people.”
