Why is this bad, exactly? Political leaders in the US undertake actions and policies that can affect the entire world, esp. in regards to military action, so why wouldn't some people abroad want to donate to a campaign? Also, given that there are several million non-citizen residents of the US, they deserve just as much input into the political process of the society they are a part of.
