A Democratic campaign that has cost more than $1 billion, dashed the ambitions of veteran politicians, forced conversations about race, gender and identity and prompted fierce debate over health care and taxes crests Monday in the Iowa caucuses.

Polls suggest that Vermont Sen. Bernie Sanders may have a narrow lead, but any of the top four candidates — Sanders, former Vice President Joe Biden, Massachusetts Sen. Elizabeth Warren and former South Bend, Indiana, Mayor Pete Buttigieg — could score victory in Iowa’s unpredictable and quirky caucus system as organizers prepare for record turnout.

Sen. Amy Klobuchar, who represents neighboring Minnesota, is also claiming momentum, while outsider candidates such as entrepreneur Andrew Yang, billionaire activist Tom Steyer and Hawaii Rep. Tulsi Gabbard could be factors.
