Abstract: | Four aspects of Donald Trump's hijack of the Republican party are examined. First, how he used unconventional techniques, usually associated with some ‘reality’ television programmes, to become the leading candidate in the pre‐primary debates. He could thereby develop ‘momentum’ before the primaries began despite his limited support among Republican activists. Second, how his insurgency differed from the party's takeover in 1964 by supporters of Barry Goldwater. Third, how the Republicans have replaced the Democrats since the early 1980s as the party with a less cohesive potential coalition among voters, with the result that internal party relations became more conflictual throughout the period. Finally, that internal conflict has been intensified by two factors in those decades: the prevalence of divided government, which has made it virtually impossible to impose a truly conservative agenda on federal government policy, and the impact of forty years of stagnating real incomes for many middle‐income Americans. |
