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.
How can you, as someone who claims to have “no delusions” about Trump’s history, not be even the slightest bit suspicious about Trump considering that just a few years ago he was praising Hillary and Pelosi(among other things)?
