Long story short: tell your Senators to pass the For the People Act, the John Lewis Voting Rights Advancement Act, and the Equality Act, and confirm USPS Board of Governors nominees; also, tell big corporations to stop donating to politicians who restrict voting rights. 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 Senators' phone numbers, or use the email/petition links in the paragraphs below. Good hunting!
Daily Kos, the Sierra Club, and People for the American Way all help you tell your Senators to pass H.R. 1, the For the People Act. Most folks aren't falling for the ZOMG TEH CHILD MOLESTURZ WILLZ THE VOTEZ!!!!! stupidity, as evidenced by polling finding that two-thirds of Americans support H.R. 1. Newt Gingrich used to say that if 70% of the people want something, they ought to get it, so only a little more education about what's really in the bill -- an end to legislative gerrymandering, automatic and same-day voter registration, 15 days of early voting everywhere, disclosure of campaign donations over $10,000, an end to particularly nefarious forms of racist vote suppression -- should get us over the hump. Even Joe Manchin might hear it then.
Common Cause, People for the American Way, and the Daily Kos Liberation League all help you tell your Congressfolk to pass the John Lewis Voting Rights Advancement Act. The bill would, as you likely know, plug the hole our Supreme Court blew in the Voting Rights Act by creating a new standard with which our Justice Department could stop vote suppression efforts at the state level (specifically, it would subject any state or locality, not just ones in the South, with a record of vote suppression for extra scrutiny). Why haven't Democrats formally introduced this bill yet, or folded it into the For the People Act? I don't know, but does it matter? What matters is what we want, and what we tell our Congressfolk.
The Daily Kos Liberation League and People for the American Way both help you tell your Senators to pass H.R> 5, the Equality Act. As we speak, states are mulling or passing bills outlawing transgender students from competing in the sports that match their gender. Of course they know no boys will become girls just to dominate girls' sports and sentence themselves not only to a lifetime of making less money playing sports but ostracization from their buddies, but as David Frum instructs us, it's not about winning, or even fighting, it's about looking like you're fighting. Let's remind them there are more important things in life -- you know, like fighting real discrimination that gay and transgender folks face all the time, like getting shut out by banks and landlords and employers strictly on the basis of sex.
Common Cause helps you tell your Senators to confirm President Biden's three USPS Board of Governors nominees, not least so they can fire Postmaster General Louis DeJoy before he runs our Post Office even further into the ground. His big, bold proposal for getting our Postal Service back on its feet: higher prices and worse service. When I say CEOs are overrated, this is kinda what I mean. Don't let folks say he's just doing what has to be done, because this is America! We don't have to have a Post Office that runs badly! Especially when they're only losing money because Congress mandates that they pre-pay 75 years' worth of benefits! It's a manufactured hostage crisis, again! OK, I've run over my exclamation point quota. Anyway, while you've got your Senators on the phone, you can tell them to pass H.R. 695/S. 145, the USPS Fairness Act, which would repeal that Congressional mandate.
Finally, since we spent a lot of time on voting rights today, Public Citizen helps you tell big corporations to stop donating to politicians who suppress votes. Much more useful, I would say, than merely criticizing them in public, though I don't say that's worthless, precisely. But as many smart people have said, these big corporations gave a lot of money to the politicians who passed laws suppressing the vote. And they've done this dance with us before: they used to say they supported the nefarious American Legislative Exchange Council (or ALEC) for "economic" reasons, not for Voter ID or Stand Your Ground reasons. It's a load of rubbish. Let's let them know that we know that -- and give them an opening to do better, for once.
