In order to win elections, the party depends on the base — largely white working-class and rural people, many resentful of big cities, liberal politics, immigrants and black people — which has now been hijacked by Trump. It is this cohort that lost its mind when a black president, Barack Obama, was elected in 2008 and, spurred on by opportunists in the Republican Party, became a populist horde identifying as the “Tea Party”.
They and others have morphed into the Trump cult, attracted by the Dear Leader’s pungent racism, authoritarian charisma and incessant lies.
