Fair point, but if the political system itself isn't capable of dealing with that sort of crap, then isn't that a problem that needs to be fixed by addressing the infrastructure of the system itself, rather than anything else? Our political institutions are supposed to reject special interests and make decisions for the national good. This, after all, is their primary function and raison d'etre. If some subset of those special interests (vis, foreign actors) need to be filtered out through some special mechanism, then what does that say about its robustness and fitness-for-purpose with respect to all the other groups trying to game the system?
