Pretty much. Whenever you say something about their candidate's past that they don't like, the venom begins to flow.
Pure, compensatory, fantasy. No one who supports Trump has any delusions about his history.
What gets under his supporters skin is Cruz supporters brooking no opposition that his history disqualifies Trump from consideration by "real" conservatives.
It's that supercilious presumption of superior intellect for thinking in tactical terms, rather than systemic, that pisses off supporters who know better.
