Unfortunately, I don't think a pure constitutionalists can win the general. They would be outright demonized by the media and the left. That old tattered rag gets in the way of their utopia. Ironic, don't ya think? That those the document protects seek to destroy it.
Like I said, I think Trump is America (at least in equal part to that portion that Hillary is America)...it's all about winning for some, maintaining the "hard fought victories already won" for others, and a relatively very few care about the Constitution.
