* Bush fabricated evidence to start a war and never got prosecuted.
* Obama's administration literally sold guns to a Mexican drug cartel for no apparent reason.
* Reagan had iran/contra
* various different "collateral damage" fuckups under every administration during my lifetime where dozens of civilians are killed but nobody cared because they're poor, brown, and not American
* Kennedy authorized the CIA to raise a private army and launch an invasion of a country we weren't at war with.
And many more, this is but a small sample of the crimes presidents have committed.
But nobody ever gets held personally accountable for anything until Doritos Hitler comes along and commits a series of crimes which, while unconscionable, are comparatively minor next to the above listed. This ruling hasn't actually changed anything. It just codified something that has obviously been true for at least 80 years, and it prevented one party from selectively applying the law to a political opponent in a way which it almost never gets applied.
So my defense isn't that the president should be above the law (he shouldn't), but that he obviously already has been above the law for a very long time and pretending otherwise is just lying to yourself and the american people.
