Yup. The GOP SCOTUS knows what an evil person would do with the power, and they carefully wrote the opinion to:
1) Excuse Republicans who will gleefully break the law, such as Trump.
2) Retain the looming threat of punishment against Democrats.
Win-win.
The ruling makes it possible for a President to be a mad king (they can take bribes, run death squads, can do any horrific act personally) but doesn't make it possible for them to be a technocratic dictator (can't tell a factory how much to pollute, except by using death squads to punish its boss).
If Dems finish with a trifecta, they are still going to be faced with "does the President have the power to call bullshit on SCOTUS?" We are fast approaching an "Andrew Jackson But Good" moment, even if we avoid a "we couldn't keep a Republic" moment.
To me it's if anything more simple. As Stafford Beer said: "A system is not defined by rules, but by how they are enforced." The GOP has been demonstrating my entire life that they don't care what law says, only how it can be used for their advantage. Dems have consistently ignored that dynamic.
