He has stated he will be a dictator. The Senate flipped Republican and there is a good chance the house will too.
With total control of the executive, legislative, and judicial branches of government, all they have to do is repeal the filibuster (very easy), and they have complete unchecked control.
They will obviously start with things that are not as bad, but they're not going to want to give up their power, and in 2 years there is a zero percent chance elections will be held democratically. They might appear democratic, but they'll resemble "elections" in Russia.
You're likely eligible for your states Medicare subsidies. Democrats fixed the family glitch in 2022, so you'll likely save thousands switching off your employer plan, even if you're making low six figures.
Of course those subsidies expire in 2025, and there is a snowballs chance in hell of those getting renewed now.
Democrats did a lot of things to improve the lives of working class, at least as much as they could get pass the Republican house.
Their problem is messaging. They are terrible at communicating what they're doing, and how it's going to help. I mean part of that problem is the media (ie fox news) is allowed to lie and Dems try to tell the truth. The playing field is not really level.
