That's because Trump is a welcome, but extremely unguided missile.

On the one hand, his great virtue is that he is a superb salesman and showman who has captured the GOP nomination and has a serious shot at the White House with absolutely no help whatsoever from the Washington/Wall Street establishment.

So unlike any other candidate in recent memory, he owns his own talking points; is not saddled with a stable of credentialed advisors schooled in three decades of policy error and failure; and has the hutzpah to trust his own instincts——many of which, especially on foreign policy, are exactly the rebuke that Imperial Washington and its legions of parasites and racketeers so richly deserve.

On the other hand, the Donald's policy thinking, if you can call it that, is thoroughly inchoate. His policy pronouncements amount to little more than spontaneous eruptions of sentiment, prejudice, hearsay, bile, applause lines, wishful thinking and disconnected non sequiturs. That's where thoughtlets like Muslim bans, mass deportations, a Trump Wall on the Rio Grande, paying off the national debt, 40% tariff barriers, obliteration of ISIS and numerous other stray verbal hand grenades come from.

Yet occasional wild pitches are not really the problem, and the cynics are surely correct in predicting that Trump will excise most of them from his patter even before the GOP convention. The real problem is that Trump has no detectable economic philosophy or policy framework, and it is in that arena that he could go careening off into a cacophony of misfires, mistakes and statist mayhem.
