I agree, broadly, but this doesn't mean what I'm saying is wrong. Cory argued that extremism is losing the right elections, and then argued that therefore the left should lean more left.

But the reason why the polling data says what it says is because of where the political parties actually are.

If you say: "Abortion is always legal, no matter why or how late", support drops to 10-25% depending on how you phrase it.

If you say: "Businesses need far more regulation", support is around 15%.

If you say: "the most important issue facing the country is racism", under 10% agree.

If you want a complete overhaul of the criminal justice system: under 25% support.

These are all positions you get closer and closer to when you abandon Biden-like centrism and move in a more progressive direction.

At some point, you won't have that supermajority any longer, even among citizens.

As I pointed out last time--and you did not contest this--it's the centrist Democrats who win elections. I grant that if we switched to compulsory voting, the center would shift a bit, but the fundamental logic is that centrism (relative to voters) wins and extremism doesn't, and progressivism points all the way into extremes that aren't popular.
