“[House Minority Leader Nancy Pelosi] knows that if Democrats are to regain a majority, it will be by winning swing districts with sensible, mainstream candidates. Ms. Ocasio-Cortez is making that task harder across America,” Lieberman wrote.

“Ms. Ocasio-Cortez is a proud member of the Democratic Socialists of America, whose platform, like hers, is more Socialist than Democratic. Her dreams of new federal spending would bankrupt the country or require very large tax increases, including on the working class,” he continued. “Her approach foresees government ownership of many private companies, which would decimate the economy and put millions out of work.”

Lieberman also took a shot at Ocasio-Cortez views on international politics. “Ms. Ocasio-Cortez didn’t speak much about foreign policy during the primary, but when she did, it was from the DSA policy book—meaning support for socialist governments, even if they are dictatorial and corrupt (Venezuela), opposition to American leadership in the world, even to alleviate humanitarian disasters (Syria), and reflexive criticism of one of America’s great democratic allies (Israel),” he wrote.
