Iowa Democrats will gather Monday night to caucus, the first Americans to officially weigh in on who the Democratic Party’s nominee to face President Trump will be.

On Sunday, the candidates actively competing for Iowa — Sen. Bernie Sanders (I-Vt.); former vice president Joe Biden; former South Bend, Ind., mayor Pete Buttigieg; Sen. Elizabeth Warren (D-Mass.); Sen. Amy Klobuchar (D-Minn.); entrepreneur Andrew Yang and investor Tom Steyer — hit their final events, trying to persuade voters to stand in their corners Monday.

In their closing arguments, Biden returned to a common theme of safety and experience, painting himself as the nominee with the best chance of beating Trump. Behind “Unite the Party” signs, Warren made an explicit appeal to women. Buttigieg pitched generational change, and Sanders sought to mobilize his passionate base.
