The Democratic Party adopted a resolution last week calling for the United States to return to being part of the 2015 Iran nuclear accord, signaling its 2020 platform will consist of re-entering the deal that America withdrew from last year.

“The United States should return to its obligations under the JCPOA, and utilize multilateral and bilateral diplomacy to achieve political solutions to remaining challenges regarding Iran,” states the motion that passed on Feb. 16.

Almost all Democrats supported the nuclear agreement and opposed the U.S. withdrawal from it in May 2018.

The Trump administration soon followed that decision by reimposing sanctions that had been lifted under the deal, in addition to enacting fresh economic penalties against Tehran.

So far, eight Democrats have declared their candidacy for the party’s nomination for president in 2020: former Maryland Rep. John Delaney, Massachusetts Sen. Elizabeth Warren, Hawaii Rep. Tulsi Gabbard, California Sen. Kamala Harris, New Jersey Sen. Cory Booker, Minnesota Sen. Amy Klobuchar, Vermont Sen. Bernie Sanders, former Secretary of Housing and Urban Development and San Antonio Mayor Julian Castro, entrepreneur Andrew Yang and author Marianne Williamson.

Pete Buttigieg, the mayor of South Bend, Ind., and New York Sen. Kirsten Gillibrand have each set up an exploratory committee and are expected to eventually announce their own official candidacies.
