Delaney, who was booed by the crowd for his comments, said “Medicare for all may sound good but it’s actually not good policy nor is it good politics.”

Ocasio-Cortez, a freshman lawmaker who has championed the progressive policy, said in a post on Twitter Sunday that it is time for Delaney to “sashay away.”

“Since there’s so many people running for President (& not enough for Senate), instead of obsessing over who‘s a “frontrunner,” maybe we can start w some general eliminations,” Ocasio-Cortez wrote. “This awful, untrue line got boo’ed for a full minute. John Delaney, thank you but please sashay away.”
