WES PRUDEN: Mr. Comey’s not very good day.

The Donald was revealed again as a man who talks too much, with a gift for the memorable insult, the demand to have his ego stroked. But didn’t we already know that? What we know now about James Comey, only suspected earlier, is that he’s what the British call “wet,” a wimp under pressure. He offered evidence at last of collusion, but it was only evidence of his eagerness to collude with his own emotions. He was incapable of standing up to Donald Trump, beyond the instinctive deference everyone accords a president.

He’s guided by his feelings, which perhaps explains why he has become a late hero of the present age. He testified that he “felt” “directed” to terminate the investigation into the activities of Mike Flynn. “I mean, this is the president of the United States, with me alone, saying, ‘I hope this.’ I took it as, this is what he wants me to do.”

One of the most telling moments of the day was an exchange with Sen. Dianne Feinstein of California, a Democrat, asking the question that Republicans have raised over the weeks of rumor and not much real news. When he “felt” that Mr. Trump was asking him to throttle his investigation, she asked: “Why didn’t you stop, and say, ‘Mr. President, this is wrong?’ “

“That’s a great question,” Mr. Comey replied. “Maybe if I were stronger, I would have.”

Comey’s testimony goes a long way towards explaining his erratic behavior throughout 2016.
