A few weeks ago, as the president received some of the highest marks of his presidency, we wrote about a “Trump bump.”

Over the past few weeks, that bump has turned into a fairly distinct slump, as President Trump’s approval ratings returned to where they were before the pandemic began.

The president’s job approval rating has slipped 6 percentage points since mid-March, to 43 percent — the sharpest drop Gallup has recorded for the Trump presidency so far, in part because the president’s ratings have remained fairly stable (and lower than the historical average for presidents of 53 percent).

In a Wall Street Journal/NBC News poll released on Sunday, just 36 percent said they trusted what the president said about coronavirus, while 52 percent did not. Voters by a 9-point margin said they thought Joe Biden would be better able to handle a crisis than Mr. Trump, and by a 9-point margin said Mr. Biden would be better at responding to the coronavirus.

And in a Pew poll, 65 percent of Americans said Mr. Trump was too slow to take major steps to address the threat to the United States when cases of the disease were first reported in other countries.

Typically, during a national crisis, leaders get a boost in their numbers, as a result of the rally-around-the-flag moment. That’s been happening both in the U.S. and around the world.

Unlike Mr. Trump, leaders in Europe and across the globe have seen their support rise to record highs. Even in Italy, one of the countries hit hardest by the virus, Prime Minister Giuseppe Conte has hit a remarkable 71 percent approval rating, up 27 points.

At home, governors are getting marks far higher than Mr. Trump, with majorities in state polls saying they approve of how their governor is handling the crisis.
