To me what is weird is the "complete" pardon from a president that is supposedly going after immigrant drug dealers and murderers.

Basically, if you've done something wrong, but can drum up enough support for the winning political candidate, you get a chance to cut a deal and wipe the slate clean.

To those that say he's rehabilitated etc, I'm sure there were other worthy prisoners too, but why does this particular guy happen to get the pardon on day one?!

Same with the pardoned capitol rioters.

It just feels like a very slippery downwards slope, where political back scratching trumps everything else.

That's why commutation is a thing. The courts have ruled this as within the pardon powers. His sentence could be changed to reflect something much more aligned with other convictions for the same crimes.

It's weird he received a full pardon from the president that is on record saying drug dealers should get the death penalty.

Yeah. That was harsh, I agree.
