Many are. This one is not. The President has sweeping pardon powers.
The solution is to strike the final phrase in Article 2, Section 2, Clause 1 of the U.S. Constitution: “and he shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment.” [1].
There isn’t a place for one-man pardons in a republic. If the courts overreach, address it through legislation. (Even the imperium-obsessed Romans didn’t give their dictators, much less consuls, automatic pardon power. Caesar had to get special legislation to overrule the law.)
With Presidents of both parties having so recently abused pardons, we may be in a place where a wave could pass a Constitutional amendment at the federal level, allowing it to be punted to the states.
