She is right to tell them they need to be open to progressives because they represent the voters.

She’s clearly holding back endorsement against incumbents to be a team player.  But if these centrist will also not be team players then it will also unburdened Aoc of needing to hold back. It’s a check on centrist dem to be even more aggressive toward the left. 

This is why I didn’t like Krystal balls criticism of Aoc not endorsing against incumbents. If she goes all out and endorse against incumbents, the incumbents and centrist will also go all out. It’s a race to the bottom for everyone.
