That’s why federal law has long banned this type of political influence by foreign entities. It doesn’t matter whether it’s Russian military intelligence, a Canadian energy conglomerate, or a collection of European financiers. In fact, the leading court decision on the topic, written by then-Judge (now Justice) Brett Kavanaugh and later upheld by the Supreme Court, involved a Canadian who wanted to print some election flyers and pass them around Central Park. As Kavanaugh explained, foreign entities “do not have a constitutional right to participate in, and thus may be excluded from, activities of democratic self-government,” including “the campaign process that seeks to influence how voters will cast their ballots in the elections.”
