“The filibuster is paralyzing the Senate. It’s preventing it from doing the very basics, such as debating bills,” said Adam Jentleson, a one-time deputy chief of staff to former Senate Majority Leader Harry Reid, D-Nev., and founder of the Battle Born Collective, a progressive interest group.

Adam Jentleson, the founder of the Battle Born Collective and a former senior Senate Democratic aide, argued in the same call with reporters that, if they ascended to power, Republicans would have no compunction about ending the filibuster if it suited their purposes.

“I think the worst-case scenario for us is to not pass the things we can pass when Democrats are in power in the hopes of preserving this defensive tool, and then having Republicans get rid of it as soon as it stands in their way and passing the bad things we’re afraid of anyway,” Adam Jentleson, executive director of Battle Born Collective and author of “Kill Switch: The Rise of the Modern Senate,” told Insider.

Today, the Senate Republicans filibustered an effort to begin debate on The Freedom to Vote Act, a compromise voting rights bill. Battle Born Collective Senior Advisor Tré Easton released the following statement in response.

“’This is her just absolutely failing to do Politics 101,’ [Jentleson] tells Molly. ‘Her constituents say they can’t reach her. There’s another story out saying all of her allies, people who supported her in her election, haven’t spoken to her in a year, and here she is popping up in Europe doing fundraising. This is not good politics, not just from a lefty perspective. This is just basic Politics 101 stuff that she is just completely failing at.’”

“’I believe we should do popular things and use our power while we have it,’ said Adam Jentleson, a party operative who now finds himself among the more vocal progressive activists in D.C. ‘But you should do them because they’re the right thing to do but not with the expectation that there would be a big political payoff.’”

“’Everybody is trying to make this marriage work,’ says Adam Jentleson, a former top aide to Harry Reid of Nevada, who was the Democrats’ Senate leader under Obama. ‘Things could get really ugly if Biden’s agenda goes down.’”

“As Adam Jentleson, who served as a top aide to former Senate Majority Leader Harry Reid, noted yesterday, McConnell’s reliance on stopgaps throughout the Obama era ‘created constant dysfunction and nonstop crises, all of which empowered Republicans, weakened Democrats, and had bad downstream policy consequences.'”

“But Tré Easton, a former Senate staffer at Battle Born Collective, a progressive group, warned that Biden and his party would be looking at ‘mutually assured destruction’ if the talks fail.”

“Adam Jentleson, a former top aide to Senate Majority Leader Harry Reid, D-Nev., and co-founder of the progressive Battle Born Collective, said it was a big deal that opposition to Sinema is ‘making the jump from the far left to the mainstream of the party.'”

The new poll from Data For Progress also finds that nearly two-thirds of Nevada voters would be more likely to vote for a U.S. Senate candidate who supports the establishment of new national monuments.

“The survey, commissioned by Battle Born Collective, gauged voter support for designating Avi Kwa Ame in southern Clark County as a national monument, a proposal that would protect 380,000 acres of indigenous cultural sites and critical habitat from future energy development and mining.”
