WASHINGTON—Determined to secure support for the Iran nuclear deal, President Barack Obama is making inroads with a tough constituency — his fellow Democrats in Congress.
A handful of key Democrats stepped forward to support the accord within hours of Obama’s personal lobbying at the White House this past week, part of the administration’s all-out campaign since the pact was announced July 14. Other Democrats have signaled they are leaning in favor and still others have remained undeclared, awaiting a vote in September.
