Passing the long overdue minimum wage increase no matter what some unelected clerk with only symbolic authority thinks about it.

And before you say it: yes I know it wouldn't pass the House right now. The point is that they didn't do It when they could, just like with almost everything that helps regular people without directly benefitting the ultra-rich and their corporations.

As for what they CAN do in spite of the House being under fascist occupation, there's also a couple things.

Like halting all weapon shipments to the fascist apartheid regime of Netanyahu, Smotrich, Ben-Gvir et al and change the diplomatic stance towards them to something more akin the latter years of Apartheid South Africa and Serbia under Milošević.

Like commuting the sentences of everyone who's imprisoned for victimless crimes such as drug possession and voluntary sex work.

Like closing the concentration camps Trump built on the southern border and revising ICE and USCIS guidelines and protocols to make legal immigration much easier and cheaper to do and provide an achievable pathway for all undocumented immigrants.

That's just off the top of my head. There's probably hundreds if not thousands of other things that they can also do with just the Senate and the White house that would fundamentally change the lives of millions of people for the better.

Then when they've earned goodwill by doing some of that, more people will vote for them, they'll retake the House and be able to do even more good and get even more votes.

It's a virtuous circle in stead of the current downward spiral.
