I just heard Donald J. Trump say two things during his rambling stream-of-consciousness rant in Bangor, Maine that tell me he’s declaring war on his political party.

The presumptive Republican presidential nominee said (a) that he’s going to tear up the Trans-Pacific Partnership and will renegotiate the North American Free Trade Agreement and (b) that the U.S. Chamber of Commerce is a gang of goons run by special interests.

Wow!

Standard GOP orthodoxy endorses free trade. Trump does not.

The U.S. Chamber of Commerce has been a traditional, deep-pocketed ally of Republican presidential candidates. Trump has no use for the Chamber.

So, what does this mean?

To me it means that Trump is kicking dirt in the face of the very political infrastructure he will need if he is going to have a prayer of defeating Democratic nominee Hillary Rodham Clinton.

What about this am I missing?

If the GOP’s presidential nominee is going to adhere to party philosophy, isn’t it time for him to at least give some lip service that endorses the views of the architects of that philosophy?

Well, hey, he said he could “go it alone” if he needed to.

It looks to me  as though the nominee is going to have a lonely march toward political oblivion.
