BYRON YORK: Measuring, and mismeasuring, the Trump conundrum.

Perhaps the most astonishing thing about Donald Trump’s victory last November was that, according to exit polls, 60 percent of the voters had an unfavorable impression of Trump on the day he was elected president of the United States.

Now, it’s remarkable that after all that has happened, Trump’s favorable and unfavorable rating — not his job approval, but whether people hold a favorable or unfavorable view of him — is virtually the same as it was on election day.

A new Marist poll, released Wednesday, found that 60 percent of those surveyed have an unfavorable view of the president, versus 34 percent who have a favorable view and six percent who don’t know.

In the RealClearPolitics average of all polls on the favorable/unfavorable question, Trump is now at 55.6 percent unfavorable versus 39.0 percent favorable. That is little changed from his average on Nov. 8: 58.5 percent unfavorable, versus 37.5 percent favorable. Among the unfavorables, that is just 1.5 points difference from then to now; among the favorables, 2.9 points.

Considering all that has gone on in the Trump presidency — it’s too much to recount in a sentence or two — the stability of the Trump favorable/unfavorable rating is notable.

It’s almost as if people have tuned out the media chatter.

Meanwhile, if you care about making a difference in politics, you should focus on the 2018 elections and ignore the daily drama around Trump.
