These three states tend to have similar results, and all three have always voted for the same candidate in recent presidential elections. However, they are now very close swing states, leaving open the possibility that they might vote for different candidates, despite the correlation and similarity in their results. The most likely scenario for this is probably Wisconsin voting Republican, while the other two vote Democratic, since Wisconsin is slightly redder than the other two. Another plausible scenario is Democratic Michigan, with the other two voting Republican, again because of Michigan's slightly bluer lean.
