We don’t know how bad the epidemic will be or how long it will last. We don’t know whether the economy will recover quickly or slide into recession.

We do know that voters — all except the most partisan ones — often judge presidents on how well they manage crises. George W. Bush’s public standing tumbled after his administration mismanaged relief efforts in New Orleans after Hurricane Katrina in 2005. Barack Obama’s fortunes sagged after the bungled rollout of his healthcare plan in 2013.

Trump doesn’t deserve blame for the coronavirus, or even for its entry into the United States, which he tried but failed to prevent.

But he surely deserves to be held accountable for his administration’s management of the ensuing crisis, just as Bush and Obama were.
