Sure, but isn’t that the nature of the beast? If propaganda works on everyone, and people get to vote, then what is the meaningful difference between propaganda and campaigning?

I really don’t see how this isn’t a system working as intended. Freedom of expression is freedom to spread propaganda.

Either the electorate is to be respected and their opinions held as valid regardless of their media consumption, or propaganda is too dangerous and effective and elections are just a farce. I’m not sure you can have it both ways.
