IDK if I would call any of the two elections you mentioned “rigged” as I feel people think of that word to mean direct fraud (votes changed for instance). That being said, seemingly both elections were influenced by Russian mis and disinformation campaigns which puts into question what the response should be. This are not honest elections and, thankfully for Romania, they are able to and seemingly are doing something about this campaign of influence. For the US, which I’m assuming was heavily influenced by Social Media during this last election, nothing should be done, except to make some changes moving forward.
