How the Iowa caucuses are changing in 2024

Five decades of tradition have been overturned by the Democrats

A SAYING IN Iowa has it that a candidate has to shake a voter’s hand seven times to win their support. Those competing in the 2024 Republican primaries have little time left for hand clasping. On January 15th registered Republican voters in the Hawkeye State will launch America’s primary season, picking the candidate they want to represent the party in the presidential election in November. Iowans have an unusual way of choosing: since the 1970s voters have gathered in town halls, school gymnasiums and church basements to make their selection, a process known as caucusing. But this year, for the first time, Democrats will choose by mail-in ballot over several weeks. They will announce results on March 5th, meaning Iowa’s caucuses will no longer be the party’s first contest. Across the country the Democrats are abandoning the traditional caucus: only Idaho and Wyoming are holding out. Republicans caucus in just six other states.
