Vote?

if your not and American citizeni dont think you should be able to vote, regardless i you are hard working or not. i think this because when people are not citizens here, but they live here, work here or whatever i feel that they are "just visiting". and say someone really really really wants john mccain or barak obama, to win they can just fly over a bunch of family members from another country and just tell them to vote, now i dont think someone would accually do this, but there are some weirdos out there. also i dont think its fair, because some one might have tried so hard to become a citizen, and say they get and they vote, but at the same time some one who can vote butis not a citizen, it would be totally unfair
