Re-entry into the nuclear deal with Iran is fast becoming a litmus test for Democrats hoping to challenge President Donald Trump in 2020.
No fewer than five declared candidates have told Al-Monitor over the past few weeks that they would rejoin the deal without preconditions should they win the presidency — as long as Iran continues to live up to its end of the 2015 pact. These include well-known lawmakers such as Sens. Bernie Sanders, I-Vt. and Elizabeth Warren, D-Mass., who both voted for the deal in 2015, along with Sen. Kamala Harris, D-Calif., who was elected in 2016.
