Long story short: tell your Congressfolk to reject any effort to repeal Biden Administration rules that benefit all of us, ignore the Musk/Ramaswamy cost-cutting commission, and let the bad parts of the 2017 tax "reform" expire. Use the tools in the upper right-hand corner of this page (or, if you're on a cellphone, the bottom of this page) to find your Congressfolk's phone numbers and/or use the email/petition tools in the following paragraphs.
The Lever reminds us that the incoming Congress would just love to repeal as many Biden Administration rules as possible, so now would be a good time to call your Congressfolk and tell them to oppose any effort to repeal said rules. These include our EPA's lead pipe rule (which would result in cleaner water and less brain damage for our children) and methane emissions rule (methane, as you recall, packs a much bigger climate change punch than coal emissions). Republicans hope you don't remember that, you know, you hate pollution, and you like clean air and water and a non-burning planet. But will remind everyone if we have to.
Common Cause helps you tell your Congressfolk to ignore the so-called Department of Governmental Efficiency (or DOGE), particularly since such a Commission would have no Constitutional power to do a damn thing (since spending laws can only come from Congress). Even our President-elect says it will "provide advice and guidance from outside of government," which sure doesn't sound like big talk. And isn't it strange that our President-elect promised to put Elon Musk at the head of the DOGE – and then put Vivek Ramaswamy at the head of it, too? Putting two egomaniacs at the head of a commission sure sounds like a recipe for disaster! Still, we can't count on fantasies of realpolitik; we can only count on ourselves speaking out.
Finally, More Perfect Union helps you tell your Congressfolk to let all the worst aspects of the 2017 tax "reform" bill expire. They weren't all bad – expanding the personal exemption was good, and we should expand it further – but even a stopped clock is right twice a day, and massive corporate tax cuts and tax cuts for the rich (all of which were bigger than any tax cut you or I got!) were terrible. These people don't need more tax cuts! They already have enough money! And cutting their taxes will mean one thing down the road: a manufactured "crisis" leading our government to try to take everything from us, like our Social Security, Medicare, and Medicaid. If we don't speak out, we can kiss all of that goodbye.
