uplifitng for two reasons:
1) He wasn't just saying things on the campaign trail (as Frank had alleged - and there was a risk of this)
and

Most of the people behind Trump in those stands are entitled rich government lifers who have had a hand in their own advancement at the expense of others. Most of them were born into their privilege as well.
Trump is the potential unlikely hero - one of them in so many ways - who appears to have sincerely come to the realization that he wants to re-empower the people. And he's not pretending and lying about their condition. Obama is a masterful speaker, but he lied constantly about the state of our economy, jobs, borders, safety from terrorism, infrastructure, and school systems (or very possibly was so privileged that he never realized it).
His speech was only dark to the status quo who don't want things to change.
