Hard to say but I suspect that Hunter will clarify his reasons in coming days. He’s had time to sit down and talk to the Huckster. I’ll trust Hunter’s instincts enough to find out why but it still doesn’t mean I’ll vote for Huck, only that I’ll hear him out.
No need to wait, IMO. Ed Morrissey has it about right when he refers to their protectionist tendencies.
I'd put matters this way:
The Dunk and the Huck are kindred souls in that they both give the impression of being closer to the anti-capitalist views of Lou Dobbs and John Edwards than to the free-market views of Ronald Reagan and Milton Friedman. This heresy sets them apart from the Reaganite mainstream of the GOP. So they end their campaigns as soulmates.
(Too bad that so many folks have invested so emotionally in the Dunk. But they'll eventually get over Dunk's betrayal. Time heals most wounds!)
