There is some good analytical data that validates that theory. I call them the Goebbels astronomers. They all repeat the same talking points, mostly lies and smears against Trumps target of the moment, endlessly, ala the Goebbels technique. And you can see this on many conservative and GOP sites, not only this one.
Yes, and the Brietbart Trump commenters are much more overtly boorish and hostile to any supporter or positive mention of Cruz. They are almost pathological in the amount of rationalizations and assumptions they will engage in, in order to make some sense of Trump’s frequent inconsistencies.
