Obama almost has the Democratic nomination locked up.  As has been discussed to some extent already, he campaigned yesterday in Missouri; today, he campaigns in Michigan.

Does anyone else consider this a small mistake on Obama's part?  Spending the rest of this week in Oregon probably won't matter much given the mail-in ballot format.  But I think he'd want to spend as much time as possible in the other states. Spending significant time in Montana, for example, could be incredibly beneficial for the general election given that it looks to be a swing state. 

Plus, while Kentucky, Montana, South Dakota and Puerto Rico are relatively small in population, it wouldn't hurt to shore up as many votes as possible for the final popular vote tally (depending on FL/MI) to deny Clinton that talking point.
