I wrote a long essay for my column this week — comparing Donald Trump’s first 100 days to Franklin Roosevelt’s — so I’m running low on takes to end the week on. But I do have two thoughts that I just wanted to get out.

The first relates to the president’s declining popularity.

We learned, at the start of the week, that Donald Trump had sunk to new lows with most Americans. According to The Times’s poll with Siena College, Trump had dropped to 42 percent approval. A CNN poll shows Trump at 41 percent and both The Associated Press and The Washington Post have Trump at 39. His much-vaunted performance with Asians, Hispanics and Black Americans is also evaporated, as they shift back toward Democrats in response to the president’s poor performance. No president, not even this president in his first term, has become as unpopular as quickly as this iteration of Donald Trump.

And it’s not as if he has the ability to shift course. He is stubbornly committed to his tariffs, almost taunting anyone who might be worried about higher prices. He is committed to his unpopular cuts to federal agencies, his unpopular attacks on the federal judiciary and his increasingly unpopular immigration policies. Given his attitudes and the likelihood of an economic downturn, Trump is more likely to crater than he is to rise with the public.

All of this was basically predictable. It was predictable that Trump would pursue a ruinous set of policies — he campaigned on them. It was predictable that he would choose people ill-equipped to run the government; he did it the last time he was president. It was obvious that he would be surrounded by permissive advisers more interested in their own narrow ideological projects than in the well-being of the American people.

It did not take a clairvoyant to see how this second term would unfold. And yet it’s clear that there are plenty of people of influence who were caught off-guard by the reckless behavior of the second Trump administration. Their initial response to Trump was to accommodate him as the legitimate president (he won a free and fair election, after all); to pare back the most strident opposition and to acknowledge those areas where he was in line with the public. Even now, in the face of everything we’ve seen, there are voices who think the right approach is a quiet one.

But to my mind, the reality of Trump’s standing — of his rapidly declining political fortunes — is evidence that the best approach was the strident opposition that marked the president’s first term. As cringe-worthy as it might have been to some observers, that posture helped undermine the administration and worked successfully to contain Trump’s worst impulses.
