The usual dementia jokes aside... of all the things surrounding this administration, this is amongst the most harmless.

It may be a "presidential" power to pardon on paper, but the reality is that unless the President (or in other countries with powers of clemency to the head of state, whoever wields that power) intervenes personally for whatever reason, petitions for clemency pass through layers of bureaucracy, reviews and meetings. And sometimes, that also includes that candidates get inserted into the process by influential aides - something that has been the case for a lot of Presidents on either side of the aisle.

Of course, the issue gets a bit more spicy given Trump's derogatory nickname of "Autopen" Biden, but leaving that aside it's no surprise to me that a US President isn't involved in dealing with clemency petitions all that much.
