It’s hard to overstate how disgusted many progressive leaders are. “It’s Senator Schumer’s job as minority leader to keep his caucus together and stand up for progressive values and he failed to do it,” Ezra Levin, a co-founder Indivisible, a left-wing advocacy group modeled on the Tea Party, told me. “He led them off a cliff. They caved.” (An Indivisible chapter is planning a Tuesday evening protest outside Schumer’s Brooklyn apartment.) Representative Luis Gutiérrez, Democrat of Illinois, said in a statement, “This shows me that when it comes to immigrants, Latinos and their families, Democrats are still not willing to go to the mat.”
