Electoral interventions

There are different ways foreign powers can get involved in elections. On the one hand, there are malicious interferences (hacking, propaganda, bribery, etc). On the other hand, there are efforts to help with planned observations or monitoring. Using readings from Weeks 1-3, consider what types of foreign interventions into elections are harmful and what kinds can help ensure a legitimate and smooth process. For the latter side of the question, you might want to review the United Nations page on election monitoring: https://dppa.un.org/en/elections. Support your answer with illustrative examples and specific cases from the sources.
