'Over the three decades following US entry into World War I, as working-class and socialist parties burgeoned throughout the industrialized world, American elites chose to deal with the problem by radically restricting access to the ballot. In state after state, petition requirements and filing deadlines were tightened and various forms of routine legal harassment, unknown in the rest of the democratic world, became the norm.
The new restrictions came in waves, usually following the entry of left-wing parties into the electoral process. According to data gathered by Richard Winger of Ballot Access News, in 1931 Illinois raised the petition requirement for third-party statewide candidates from one thousand signatures to twenty-five thousand. In California, the requirement was raised from 1 percent of the last total gubernatorial vote to 10 percent. In 1939, Pennsylvania suddenly decided it was important that the thousands of required signatures be gathered solely within a three-week period. In New York, according to one account, “minor-party petitions began to be challenged for hyper-technical defects.
"Although these statutes have been assailed on all sides,” a 1937 Columbia Law Review article reported, “their severity is constantly being increased, probably because the interests oppressed seldom have representation in the legislatures.” Indeed, when the Florida legislature found socialists and communists advancing at the polls, it responded in 1931 by banning any party from the ballot unless it had won 30 percent of the vote in two consecutive elections; naturally, when the Republican Party failed to meet that test, the state immediately lowered the threshold.
By comparison, in Britain getting on the ballot was never a major concern'
