There's another aspect to this... the user in question lives in New Zealand. Should their foul-mouthed tweet to a US Senator during a US election have the same protections as an American's tweets?

It's not immediately apparent that he's from and lives in New Zealand unless you really dig through his content, something most readers won't do. In aggregate, this might influence American voters into thinking there's some substance to anti-Palin rhetoric.

Isn't that a form of foreign influence?
