If you want something more hands on, work on local races this year. They are how we can fight back

Elections are run at the state level in the US. Even for federal offices

Many states have elections this year even despise it being an off year

There are special elections today in Virginia thay will determine who controls the state legislature. If dems remain control, they can block a lot of the Republicans governors attempts to disenfranchise

There are special elections in Minnesota on Jan 28th to determine control of one house of the state legislature

There is an election that will determine control of the Wisconsin state supreme court on April 1st. The more recent Progressive control has lead to Wisconsin getting fair maps as the gerrymandered maps were overturned. We are going to want to keep it that way and build further

There are special elections for various US house members like to replace Matt Gatez on April 1st. Should we win any suprise flips, it will be even harder for Republicans to get things through congresss with their already tight 3 seat majority

And so on

Here's a frequently updated spreadsheet with various at home volunteering options

EDIT: also on another note, consider running for election yourself. There are various small local positions around you that often go uncontested. Here's one group that helps progressives run for local office https://runforsomething.net/
