Overseas US voters get ignored by political campaigns but could be crucial supporters

I don't know how much I'd rely on Americans abroad as a voting bloc, though. From my own experience as one such person, you're just as likely to have people who want positive outcomes in the US as negative ones.

A lot of expats might maintain ties to the US and still care about American issues, but I know a heck of a lot of them don't care at all. A lot of Americans left the US because they hate it there and might even prefer it if the election makes things worse. Not that such people would be likely to vote anyways, but you're not going to find consistent voting trends from people living abroad, even if as a sum they are greater than the margin of error of some elections.

I live in Canada and not only did I receive 3 phone calls, but also 3 pieces of mail making sure to vote. By the third/call letter, I asked them to please not waste their time because I had already sent my vote in for Michigan :D Their energy and time could be spent on other calls/mail. :)
