Leaving aside the difference between "bringing charges" and "successfully bringing charges," there's a big gap between "easy" and "impossible." Nobody wants presidents to be criminally liable for the things they do in good faith. But this ruling makes good faith irrelevant; it doesn't matter why they do an official act, it's immune.

The fact is that a former president exerted pressure on government officials in a way that would halt a lawful election and coordinated to subvert its true results by presenting fake results. In determining whether that was an official act, we cannot reference his motivations according to the SC's ruling.

Allow the motivation for official acts to be taken into consideration for prosecution, and a lot of the problems go away.
