By 1968, that annus horribilis when Johnson cracked from the pressure of mediating an increasingly centripetal Democratic Party and Kennedy fell to an assassin's bullet, two political ideal-types had  a silent majority who supported Johnson's war on Vietnam and voted in Richard Nixon, and a new class of liberal professionals and youth who supported Johnson's war on poverty but detested everything Richard Nixon represented.
Some people supported Johnson and voted in Nixon and regretted it immediately.
