Treason against the United States, shall consist only in levying war against them, or in adhering to their enemies, giving them aid and comfort.
By some mysterious oversight, malicious, intentional disruption of the voting process got left out of this definition.
(And, for that matter, all other forms of political corruption.)
In game development, we always prioritize crash bugs the highest, before all other bugs, because (a) you can't ship with a crash bug (mostly), and more importantly, (b) crash bugs intefere with testing everything else. If the game always crashes when you try to cross this bridge, then you can't test any of the stuff that's on the other side of the bridge. So it's important to fix those first, ASAP.
In the same way, it seems to me treason is like a crash bug; it disrupts the basic functioning of the state, and needs to be addressed incredibly harshly, serving as a severe deterrent. And it seems to me that political corruption and vote disruption interfere with the basic functioning of the state in the same way.
