Mr. Castro announced his endorsement on Monday morning, just days after he ended his own bid for the White House. In a statement, Mr. Castro cast Ms. Warren as the logical extension of his campaign’s social-justice-driven message, which seeks to correct inequities through targeted policy proposals. He will campaign with Ms. Warren this week, joining her Tuesday night at a rally at Kings Theatre in Brooklyn.
Today I'm proud to endorse @ewarren for president.— Julián Castro (@JulianCastro) January 6, 2020
Elizabeth and I share a vision of America where everyone counts. An America where people—not the wealthy or well-connected—are put first. I'm proud to join her in the fight for big, structural change. pic.twitter.com/xDvMEKqpF3
Ms. Warren has fallen from her polling peak in early October, when she was hailed as the race’s ascendant front-runner and the standard-bearer for the party’s progressive wing. National polls now show Ms. Warren firmly in third, behind former Vice President Joseph R. Biden Jr. and Senator Bernie Sanders of Vermont, who has been aided by grass-roots progressive groups and by some high-profile endorsements of his own, including from popular House members like Representatives Alexandria Ocasio-Cortez of New York and Ilhan Omar of Minnesota.
It is unclear whether Mr. Castro’s name carries similar political weight. His presidential candidacy struggled to break through in a significant way, but he led the field on a number of progressive issues, including reparations, border decriminalization and housing inequality. He impressed liberal activist groups like the Working Families Party and the Center for Popular Democracy, even though they formally backed Ms. Warren and Mr. Sanders.
Ms. Warren thanked Mr. Castro for his support on Monday, calling him “a powerful voice for bold, progressive change.”
