Can a president pardon anyone including those who commited treason, were traitors or murderers? No limit to the power of the pardon?

Yes m'dear I realize that. The question is what is the extent of the damage he can do? Unlimited methinks. What think you? Thank you for your reply Shuhak! :)

Unfortunately, we’re going to see what he can do.  As soon as he's booted from office (November) he's going to trash this country.  He’ll pardon everyone, pass “proclamations” favoring himself (future money), fire any and everyone he can, appoint more of his cronies …. You name it and he’ll do it.

OMG Shuhak! TWO WHOLE MONTHS TO DO ALL THE DIRTY DEEDS HE CAN COME UP! TWO WHOLE MONTHS? TWO WHOLE MONTHS. Oh dear. What are we gonna do then? Thank you for your scary as heck reply. Something else to be terrified about...his potential for Armageddon on his watch. What will be left of our country? This post was edited by RosieG at May 31, 2020 11:49 AM MDT

2-1/2 months.  Inauguration day isn’t until January 20.  Of course he’ll spend most of November tying to overturn the vote - declaring it fraudulent or biased (fake?), demanding recounts (trying to prolong his term in office), calming vast percentages of eligible voters went allowed to vote or voted multiple times, … anything he can think of to try and invalidate it.

I read that the don of johns will simply REFUSE to give up his power. I wonder how he will manage to effect that? Command the military to surround the White House and SHOOT TO KILL? I put nothing beneath him or past him. He is deranged as are his adoring worshippers. I don't see a happy ending. The folks who voted him in are the ones we have to thank for this monstrous turn of events. We KNEW he'd be terrible. We just did not know how evil nor that he would have co-opted all checks and balances and eviscerated all opposition. Now we just sit and watch. Dark vision I know. Hope I'm totally wrong. Thank you for your reply Shuhak.
