Damage control on the deficit and political suicide at the same time. You can pass off the stimulus to Biden and blame him for the deficit but Biden’s name will be on the checks that help people, not Trump’s. And blaming Trump for the deficit that he doubled shouldn’t be as difficult as it may have been in the past. People know he was a disaster, even if they defend him
Of course there’s nothing urgent to do in his mind – the SCOTUS is now packed, and can (as with Bush v. Gore) declare Trump the “winner” on some pretext or other. Then they can really go wild, without even having to pretend to respect the Constitution, the rule of law, the principle of separation of powers, or any of the rest of that inconvenient stuff – known to sane people as.
