I am afraid you are in a distinct minority on the issue of rich Lowry. At least based on all of the comments. I have read only one that defends him—you.
Minorities are not always wrong. Why not review the many articles he wrote since November 2016?
You will see that he is not always a Trump basher. Besides, as an editor of NR, if he were totally against Trump, why would he allow writers who defend Trump like Victor Davis Hanson and Andrew McCarthy to be published?
That alone is evidence against the accusation that he is a NeverTrumper.
