The fact that he's anti-Trump just show that in his mind, Trump does not hold the same conservative values that he does.   Not liking Trump doesn't make him dishonest or traitorous.   He's not the only Republican that doesn't like Pres. Trump.

I've read Gerson for as long as he's been published.   His article very much sounds like Republican policy that I've known most of my life.     Republicans don't like authoritarian government design either.     Gerson is also focused on foreign policy on this one.

People change over time, I don't have the same political view as I did 20 years ago.
