> If he loses his brand is immensely toxic and no business/brand will want to do business with him.
As if the usual short-attention-span media and population will ever care about it. It'll be maybe until a couple of months after Clinton's inauguration and no one gives a f... about Trump any more. There's always something more newsworthy than the misery of a failed presidential candidate.
The only exception will be the GOP: they're in for a couple very nasty years, divided between a couple remaining "ordinary" conservatives, the Trump/Tea Party extreme-right-wing movement which surely won't be retreating even if Trump loses, and a society that is more and more moving towards the left end of the political scale - just look at marijuana, homosexual marriage, abortions... society is on a way towards progress and you just can't sell abortions and homosexual marriages to a party consisting of (extreme) Christians and right-wings. No one will vote for them any more.
The GOP will be shattered, the only problem is that there's no one to fill the gap yet.
