Ignore all polls from espn (really all online polls). They are so easily manipulated it's ridiculous. You can find the source code for a fairly effective bot on these very forums.
I can't stress this enough: if you are a human clicking anything on an online poll you are just wasting huge amounts of your own time. You won't make a difference when a single computer can do that a few times a second and multiple computers can do it thousands of times a minute.
I won't get too technical, but the reason they register as international votes is because bots don't run espn's geo-location javascript code (they aren't web browsers) and that code simply makes votes without a known location register as international.
