In case you missed it, "Democratic" Senator Joe Manchin has come out specifically against protecting voting rights and filibuster reform:
Manchin: “I believe that partisan voting legislation will destroy the already weakening binds of our democracy, and for that reason, I will vote against the For the People Act. Furthermore, I will not vote to weaken or eliminate the filibuster.”
Presidential administrations typically lose seats in the House and the Senate in the mid-term years that follow, in our current case, next year, 2022. If you think things are not going well now, consider a Congress controlled by Speaker Kevin McCarthy and Senate Majority Leader Mitch McConnell.
It is not too early to get involved in building a stronger Democratic majority in the Congress in the 2022 mid-terms. Start by voting this year and encouraging your friends, family, and neighbors in New Jersey and Virginia to vote too. You can also start supporting campaigns in key states where current Republican Senators have announced their retirement, are facing strong competition from Democrats or Democrats who must seek full terms. This includes:
Pennsylvania (where Republican incumbent Senator Pat Toomey is retiring)
Ohio (where Republican incumbent Senator Rob Portman is retiring)
Wisconsin (where America's arguably worst Senator, Republican Ron Johnson, is running for re-election)
Florida (where Democratic Representative Val Demings has decided to challenge Republican incumbent Senator Marco Rubio)
Arizona (where newly-elected Democratic Senator Mark Kelly must run for a full term)
Georgia (where newly-elected Senator Reverend Raphael Warnock must run for a full term)
In the House, 19 candidates who openly identify themselves with the QAnon movement have announced runs. They are not far from the center of the Republican Party of today, which adopted no party platform for the 2020 Presidential election and seems dedicated only to opposing anything Democrats support. Historically, Republicans have a better than even chance of returning to congressional majority power in 2022. If you as a Democrat are ready to act, you should be able to find an ActBlue account to support the candidate(s) and/or campaigns of your choice. The WI Democratic Party, for example, has set up a victory fund that welcomes small regular monthly contributions for whoever wins the eventual Democratic nomination for Senate. Post Cards to Voters is already working to encourage Democratic voters in Florida to register to vote by mail to overcome voter suppression by Republicans there.
