Institutions don’t typically collapse under sudden attack. Rather, 'if a charismatic outsider emerges on the scene, gaining popularity as he challenges the old order, it is tempting for establishment politicians who feel their control is unraveling to try to co-opt him' ... So far, Trump has been extremely long on demagogic bluster but rather conventional — if extremely right-wing in some respects — on policy.
