LOS ANGELES - A Hollywood “Dembargo” on political donations has ended, as key fundraisers and celebrities from rapper Cardi B to Oscar winner Jamie Lee Curtis and TV producer Shonda Rhimes endorsed Kamala Harris as the next Democratic nominee for US President. Relief and excitement spread across Los Angeles, the world’s film and television capital and an important source of Democrats’ campaign funds, following President Joe Biden’s decision to end his reelection campaign on Sunday. “Lost” producer Damon Lindelof said he had halted what he called a “Dembargo,” a call for Hollywood backers to stop donating money to Democrats after Biden’s disastrous debate performance in June. Lindelof, writing on Instagram, said he felt “profound relief, gratitude ... and then, for the first time, genuine excitement for the election ahead” after Biden’s withdrawal. Hollywood often is described as an “ATM for Democrats.”
