Politico indicates that besides the Progressive Caucus, the middle of the road Dems also have or are working on an agenda of their own.
It is encouraging to see such varied agenda proposals. It is something you're never get from any Republican group, or from the Trump administration. Can you imagine JD getting into specifics rather than platitudes without substance? This movement should pressure attention from the public and from the Republicans. Don't let them stonewall.
Expect growth of interest in detail ideas vs spin and obfuscation.
