Trump has faced what to all appearance has been a Perfect Storm in the last week... under attack from all sides, inside and outside the Republican Party. It would ruin most campaigns, but Trump has something going for him.. the utterly bleak prospect of a Hillary Clinton Presidency.
America and the West are in an existential crisis. Hillary offers absolutely NO change in course. She proffers disorder, dissolution, death, collapse.. in the arenas of economy, country, family, culture, social order.. all under insidious attack.
There are underlying currents in history which regenerate the root systems and the civilizational impulse of societies. We've seen that throughout the primary process as the anger at current disorder of things has bubbled to the surface.
For all his faults, and there are many, Trump is at heart a fighter and a nonconformist. I would call him a warrior and rebel. Hillary is a courtier, completely conformed and subservient to graven idols and manners of the zeitgeist orthodoxy of our times. Nothing will change under her, and drift toward destruction will go on unabated.
I expect Trump will rebound.. and win.. or we better start looking for shelter.
