I think the blue team has been in a cold civil war since 2016. They can't come to terms with their progressive hegemony ending, but also can't pivot to a new politics because elections are too close to risk a mass preference cascade needed to revitalize the party.

I think the red team is only now starting to come to similar terms, and will increasingly do so as the blue team continues to maximally exercises power against their opponents instead of revitalize the tarnished reputation of instituions.

Around 2030, the US will need to spend 100% of it's tax revenue to service the debt, and California will need to a federal bailout or risk either default or wiping out their state pensions. I believe the coming financial disaster will likely be the catalyst that quiets the 'nothing ever happens' crowd, and both teams will need to reset their politics to the new world, distinctly different than the post-WW2 open society liberal consensus.

A similar phenomenon is happening in Europe.
