These laws, though well intentioned, seem to sometimes struggle in the modern context. In this case, President Obama flew over to London in April 2016 and advocated very publicly, that Britain should remain in the EU. This act by a foreign leader was converted into headlines, videos, tweets, etc. which were shared roughly a bajillion times. President Obama is an extremely popular man. In any list of the world's most popular and influential leaders he ranks in the top 10, probably the top 5. His endorsement, if equated to USD or GBP, would equal roughly several bajillions. As far as I am aware, existing campaign finance laws do not address this kind of "free media", and that is a problem. Sometimes you need to be able to muster the resources to advocate your position with equal reach to that of your opponent, and that costs money.
