The debate over whether to call Donald Trump a fascist, and why it matters.

Quoted: Stanley Payne, a University of Wisconsin historian of Spain and author of A History of Fascism 1914-1945, agrees that Trump’s lack of coherent revolutionary fervor makes him fall short of fascism. “Never founded a new fascist party, never embraced a coherent new revolutionary ideology, never announced a radical new doctrine but introduced a noninterventionist foreign military policy,” Payne wrote to me in an email. “Not even a poor man’s fascist. Ever an incoherent nationalist-populist with sometimes destructive tendencies.”
