I'm leaning more and more towards the notion that this isn't a caricature. That this really is a sizeable plurality of the GOP primary voter.
I mean, why else would the birther nonsense be so prevalent? Or the talk about the 'gibsmedats'? Or the reformation of Pat Buchanon (who was booted from the GOP by Buckley for his anti-Semitism)?
Why else would Trump get favor by calling to strip US citizens of their citizenship?
