I suspect that the idea originally was to give some safety valve but if it is used more than a few times by a President, it makes a mockery of it and it should be removed as a power. How can a President ever decide that the entire legal process is flawed and their opinion is right? If the sentence was too long then change the sentencing guidelines.
1500 in jail for protesting in DC? Really, less than that in jail after months BLM riots afaik. Sure, jail a few bad boys, but 1500? No way.
Throw a rock at people in power and go jail. Rape and murder is fine, no threat to DC.
Trump and his minons tried to undo the results of an election. An election he lost. Lost even while abusing his power as president (see his calls in Ukraine and Georgia as evidence).
Nobody on the left supports looters or rapists. If there is evidence someone committed a crime, prosecute them. Trump is the only person I know that supports rapists (see Epstien and Gaetz). He says if you are loyal to him, you don't have to face the consequences of your actions. That to me is what is most scary.
