Thats true,but progressive voters want more progressive actions .There are a lot of progressive voters who are tired of moderate democrats,has been for awhile.Millions of progressive voters stayed home or voted Nader in 2000.Obama was ok so they came out for him.Millions of progressive voters stayed home or voted Jill Stein in 2016.A combination of Trump and Biden running farther to the left of Obama got progressives out in 2020,but we realized we have been duped and wont be falling for a guy who was a moderate his entire career then promises to be progressive when running for president.
The number of these progressive or bust democrats are growing.Personally I have voted for the democrat nominee my entire life,but from now on if the democrat nominee is not a progressive who has been a progressive their entire career I will be voting for The Green Party nominee.
