Reelected? He didn't even want to be president in the first place. Most likely he ain't going to make it there either health-wise or politically, but in case he does, he will use an excuse for not running. I don't think even Reps would want him to run again, they would rather pay off his debts...
I mean seriously, the fucker already can't put a normal sentence together, add in 3 years of Alzheimer/dementia and we are talking about changing diapers...
