Of course he’s a token.
No white guy with his thin resume would be taken seriously as a candidate for POTUS. A speech or a book isn’t enough.
But even if he had the resume, his support for open borders places him squarely in the Reject bin, along with fellow invasion supporters like Jeb and Hillary.
