Ann Coulter swore fealty to Donald Trump a long time ago. But her desperate and brittle defense of him has revealed her dark and ugly side.

Coulter’s writings held a mocking sharpness for years. The mocking has gone. Now there’s just a razor blade, casually slicing up everything wherever it goes, little caring if she wounds friend or foe, so long as she serves Trump with the devotion one should only pay to one’s Creator.

We should have all taken heed of that when she tweeted this out a year ago.

I don't care if @realDonaldTrump wants to perform abortions in White House after this immigration policy paper. http://t.co/l7nq8gN7i5

And many did. But it wasn’t enough. Trump may have finally upset Coulter now about immigration, but it wasn’t before her new book, “In Trump We Trust,” has gone to print.
