Political reality can change with alacrity — and radically so. Consider what happened in Germany between 1928 and 1933. In the elections of May 20, 1928, the National Socialist Party received a miniscule 2.6 percent of the popular vote, winning just 12 out of 491 seats in the Reichstag. By March 5, 1933, the date of the fifth national election in as many years, the Nazis' share of the vote had swelled to 43.9 percent, giving the party 288 seats out of 647. The single most salient variable in the changing electoral fortunes of fascism in Germany was the stock market crash of 1929, which delegitimized the parties of the center and boosted support for the ideological extremes.
