What did they say under Biden? Because, first, these numbers are kinda crazy how split the country is despite the horrors we see around us.
But also, I think the issue is voters are able to see things are not going well but they're mostly not educated enough articulate a better alternative. So instead they just wish for the only other option they're aware of, which is the party out of power.
If we want to break this pendulum cycle, we need to articulate a better alternative that speaks to the concerns of ordinary voters and help them build the tools to actually implement it. I don't have much hope for such a movement under either party, nor among any third party due to the way our elections punish third parties. So it may need to exist outside of national electoral politics.
