On Friday, the Trump campaign launched a new website under the title “Barely There Biden.” It said it would show “Joe Biden’s descent into incoherence.”

In an email to reporters announcing the website, Trump 2020 communications director Tim Murtaugh asserted, “Anyone who watches Joe Biden speak for more than a minute can tell that he is barely there.”

The Trump campaign — unusually for an incumbent candidacy — is also pushing for more televised debates than normal. Politico reported on Thursday that the president’s team would press for four debates rather than the customary three.

On one hand, that is evidence that the president’s team believes Biden could crumble under the spotlight. On the other, it is a sign that Team Trump realizes the height of the hurdles it faces. One of the standard rules of politics is that the candidate who is trailing wants more debates and the candidate who is leading wants fewer.
