This is good: America’s Victim in Chief.

Imagine growing up heir to a fortune in New York City, attending an Ivy League university, marrying a series of models, getting paid millions of dollars to host a reality-TV show, getting elected president … and then constantly casting yourself as a victim.

That apparent compulsion is defining Donald Trump’s presidency.

Scarcely a week goes by without Trump whining that he has been mistreated by the media, a political rival, a TV personality, or a legislator. He is John McEnroe; the presidency is his U.S. Open. We are the crowd, transfixed in spite of ourselves by unnerving tantrums, which betray the fact that he is too volatile and too weak to master himself.

His victim mentality is deepening along with Robert Mueller’s probe.

McEnroe would most likely object to the comparison, but it’s a good one.
