Who is this and what did he do with Trump?

I think pretty much all political speeches are bullshit but still appreciate if someone can deliver it without looking like an idiot.  And trump generally excels at talking like a stumble-bum.  But I have to give him credit for this speech.  I think it was a good summary of his positions, the challenges he sees coupled with hope for the individual, and it was delivered with any hitch.
