After the second debate, I think Trump has decided to go full Alt Right for the remainder of the election.
His performance was Breitbart all the way down.
I wonder how the old party will wear it. They are on the cusp of the destruction of everything they were and thought their voters believed before this election cycle.
You can trace the rise of this voter bloc back through the Tea Party years and beyond. Trump is the Frankenstein's monster leader which that movement created. He is who they are.
It is unlikely to win an election. But the Trump-Breitbart-Drudge team seem to have plans for its use afterwards.
