I don't think he'll be re-elected, should he run again. I don't think he'll be able to 'fix the economy", which seems to be the main reason why most of the rural areas that voted for him (if you look at the votes of each state). For instance, coal mining is just a dying industry. The people aren't going to get better jobs, which will lead to the same dis-satisfaction of why they initially voted for Obama but not for Hillary.
Well, scratch that, he *could* get re-elected if the people want to give him a full 8 years' chance, but after that, I don't think a person trying to deliver the same message will have a chance.
