I wouldn’t make any predictions – what is predictable is that the unpredictable happens. In other words, sh*t happens.
There are any number of very nasty situations that may explode in Obama’s face.
Obama is a con man & a liar, a total phoney, and as you say, a narcissist. He’s intellectually shallow & not particularly competent, an amateur.
The world has become far more unstable than it’s been in 75 yrs.
Obama may be over-taken by events, events over which he has no control & no competence to deal with.
Sure, it’s possible Obama can fool the electorate again provided there is no major crisis. But, it’s in no way inevitable.
