This topic has almost never been addressed before, and it wasn't a mistake. Grant County is very small and it's not surprising that you'd see odd results there.
Thanks Vander.
If I may ask, did Barr spend time campaigning there, hoping he could win at least one count?
No, Blubb is lying. Never listen to him, he's a troll.
It's a mistake. The county has acknowledged it was a mistake. In one precinct, they counted McCain's votes for Barr and Obama's votes for Baldwin. But the state certified the results before the mistake could be rectified, so it's now official.
