With Debate Deal, Trump and Biden Sideline a Storied Campaign Institution

The agreement by President Biden and Donald J. Trump to move ahead with two presidential debates — and sideline the Commission on Presidential Debates — is a debilitating and potentially fatal blow to an institution that had once been a major arbiter in presidential politics.

But the roots of the commission’s decline go back at least a decade and came to a head in 2020, when the commission struggled to stage a debate with Mr. Trump and Mr. Biden during the pandemic.
