It brought to my mind Peggy Noonan's observation last summer, following Donald Trump's victory in the Republican primaries. I quoted it on Radio Derb at the time:
From what I’ve seen there has been zero reflection on the part of Republican leaders on how much the base’s views differ from theirs and what to do about it. The GOP is not at all refiguring its stands.Ctrl-F on Wehner's piece with the text string "immigr" yielded no hits.
If there is anything that needs challenging, it is the notion—implicit in that omission—that the U.S.A. needs two major political parties committed to open borders. What would be wrong with just one?
