How serious is the Biden-Harris Administration about its own agenda, especially on voting rights?

What the Biden-Harris Administration will turn out to be is obviously still an open question. There have a been some very constructive moves, like the COVID relief and stimulus bills. Having foreign policy run by a President who is not primarily focused on benefitting his own private businesses thereby is a good thing, by definition.

But At Least They Are Better Than Trump is way too low a standard for any Presidential administration, and certainly for a Democratic one.

This AP report gives a strong hint that Biden and Harris may have abandoned the idea of a new voting right law this year, As Frustration Mounts, a White House Push on Voting Rights 07/09/2021:

President Joe Biden met with civil rights leaders Thursday in the West Wing, while Vice President Kamala Harris announced $25 million in new spending by the Democratic National Committee on actions to protect voting access ahead of the 2022 midterm elections.

Biden and his team stress ongoing legal efforts to safeguard voting rights. They’ve also promised a major legislative push after Senate Republicans blocked a sweeping election overhaul last month. The president has told reporters he plans on “speaking extensively” on voting rights and that he would be “going on the road on this issue.”

Friday, the White House announced that Biden would travel to Philadelphia on Tuesday to discuss “actions to protect the sacred, constitutional right to vote.”

White House press secretary Jen Psaki said the president will “go to the birthplace of democracy to make the case for the moral imperative of making voting more accessible to people across the country.”

He goes into more detail in this video, Ryan Grim: Registering Voters Is NOT A RESPONSE To Voter Suppression The Hill 07/12/2021:

The segment includes this observation:

.@ryangrim:"Compare LBJ's approach to Biden's. When LBJ was being counseled to just drop the issue by his advisors...he shot back, 'well what the hell is the presidency for?' Biden’s answer so far is that the presidency is for selling voting rights merch." https://t.co/Mxf05MgipH pic.twitter.com/c07seyzl4M

There are other critical priorities for legislation, including a substantive infrastruture bill and a real beginning on a Green New Deal infrastructure effort.

But voting rights legislation is critical. And ConservaDems are quick to start mocking demands to fight for legislation that may not be a sure thing as "Green Lantern" fantasy. But if the President isn't willing to fight for legislation to prevent the most widespread attempt at racist voter suppression since the 1870s, then he's just not serious about it.

Congressman Jim Clyburn of South Carolina recently told Mehdi Hasan that he was hopeful that substantive voting-rights legislation would pass. But in the same interview, he went on to make the bizarre statement that the defund-the-police notion has a "chokehold" (?!?) on the Democratic Party. Jim Clyburn: “Defund The Police” Has “Chokehold” On Democrats 07/09/2021:

The combination of not being serious about passing voting rights legislation and sneering at activists protesting against police murdering people is a bad one. The political danger is not that constituencies like African-Americans who currently lean Democratic will suddenly take a liking to Republican that are babbling in a cult-like way about "critical race theory." The danger is they will be discouraged or disgusted enough that they won't vote in their usual numbers. And in 2022, the Democrats seriously need their voters to turn out in number higher than the usual rate for midterm elections.
Mark Elias is leading the legal effort that is at least nominally supported by establishment Democrats to counter Republican voter-suppression laws in the courts. But it doesn't replace a voting right law. You can follow his Twitter feed for updates:

In the article linked there, he emphasizes how important and urgent new legislation is:

Though Congress has taken notice, progress has been difficult. While the House of Representatives passed the For the People Act (H.R. 1), which would preempt many of the worst of these new state laws, passing it in the closely divided Senate has so far proved more difficult. Additional legislation is also in the works — including the John Lewis Voting Rights Advancement Act, which would restore a critical portion of the Voting Rights Act that was struck down by the Supreme Court.

While most of the legislative focus has been on the registration and voting process, significantly less attention has been paid to another point of vulnerability in our election system — the rules for tabulating and certifying elections. The right to vote is hollow if it does not include the right to have your vote counted and, if your candidate receives the highest number of votes, to have her assume the office to which she was elected. Republicans are taking aim at this vulnerability. [emphasis in original]
