Polnut, I like everything about your suggestion except for §2.
I find it disturbing that anyone would support penalizing an elected official over something as vague and subjective as "ignoring the GM." This skews too close to criminalizing independent research and unpopular opinions or interpretations of events. We already have a way of holding officeholders accountable for their bad policy decisions... elections.
In any case, this is an issue that deserves to be treated separately from this amendment, which was originally concerned with protecting the GM from executive overreach and sparing the President from angst over the political consequences of retaining any particular GM.
It's only in broad terms... this isn't an amendment, just outlining ideas.
