“Let's face it: The atmosphere in this place — it's a hostile work environment,” said retiring Rep. Ron Kind (D-Wis.). “We've got members threatening to kill other members and treating each other with such disrespect.” And he added: “Things seem to be getting worse.”

The retirement of DeFazio, chair of the House transportation committee, sent a shock wave through a caucus already clinging to its small majority after months of infighting. The departure of a high-profile gavel-wielder, whose seat became much safer in redistricting, has left many Democrats asking the obvious question: Who’s next?

Even those who plan to stick around for another term are less than enthusiastic about it.

"If you've been here a long time, it gets old after a while,” said Rep. Kurt Schrader (D-Ore.). "Especially with redistricting and the likelihood of us potentially losing the majority, a lot of folks … are looking at this as the high-water mark."

“This place is a slog,” added Rep. Scott Peters (D-Calif.). “People maybe thought that being in the majority would solve all the problems, and it's hard, too.”

Senior Democrats are quick to acknowledge that not everything is sour. Their party — which unexpectedly captured full control of Congress less than a year ago — is on the cusp of a once-in-a-generation expansion of the social safety net. Democrats singlehandedly passed trillions of dollars in pandemic relief aid this past spring. And just weeks ago, the two parties agreed to a massive infrastructure bill blessed by both Biden and Senate GOP Leader Mitch McConnell.

On the political side, Democrats are poised to pick up a couple of House seats with a favorable new map in Illinois. They have landed a few strong recruits in swing districts in California and Iowa and maintained their strong fundraising, though Republicans have started to cut into their advantage.

But looking ahead to the next few weeks, Democrats sound like Scrooge as they stare down grim battles over government funding, a debt crisis and the fate of their sprawling safety net bill. Not to mention a 2022 that many in both parties expect will end with Democrats toiling in the House minority, devoid of political power.

“Most people don't get elected to be the goalie" in the minority, said Rep. Mark Pocan (D-Wis.), recalling his previous time in that wilderness. "Most people want to get out there and do something, and that's why they run for Congress. And that's the biggest challenge."

Some senior Democrats say DeFazio’s retirement reveal, which came as a surprise to even some of his longtime friends in the House, could be the first bell of a holiday rush.

Unlike some of his colleagues this cycle, DeFazio’s decision didn’t appear to be driven by a calculation about his own future in elected office. After a tough 2020 reelection, his seat was redrawn as a seat that Biden would have won by 13 points in last November's election — rather than 4 points.

Instead, Democrats close to him say his departure is more of a reflection of the party’s potentially unappetizing future in the minority, particularly as committee leaders see their powers diminished or quashed all together.

DeFazio, whose life's work has been roads, bridges and rail policy, already took a blow from his own party this year when an infrastructure bill he labored to craft was shunted aside during a Senate-driven push. Known as a blunt talker, he didn’t hold back, blasting the Senate bill as “crap” and saying he “could give a damn about the White House.”

He’s far from the only House chair frustrated to see the dysfunction of a 50-50 Senate complicate life across the Capitol. Manchin couched his "sucks" criticism in a moment of bitter partisanship from the Trump White House three years ago, but the Democratic-controlled upper chamber has taken its own toll on the party's House members.

“It takes a lot of the sense of power that you have, especially as a chair,” said House Budget Chair John Yarmuth (D-Ky.), who is also retiring next year.

“I’m a new chair. But I can tell you it’s hard, especially when you have smaller margins, trying to get things done,” added the House Foreign Affairs Committee's chief, Rep. Greg Meeks (D-N.Y.). “The climate here has changed.”

But it’s not just the transportation committee. Several Democrats say they have private lists of senior members who they believe could head for the exits between now and next spring. Some, like other committee chairs, would further rattle the caucus and could affect both candidate recruitment and fundraising at a critical time for the party.

A significant number of older committee chairs who have served for decades or seen their marquee legislation enacted this Congress — or both — are on the retirement watch list. But for now, they’re not joining DeFazio.

“I’ve been a part of what’s turned out to be a pretty good ride,” House Ways and Means Chair Richard Neal (D-Mass.) said in an interview on Wednesday, ticking off a list of high-profile achievements in the majority from the North American trade deal to health care reforms, the slew of coronavirus relief bills and Democrats’ social spending package.

Has Neal thought about retiring too? “I don’t have any plans to say that,” he responded.

Most painful for Democrats are retirements by swing-seat members like Kind, Rep. Cheri Bustos in Illinois and Rep. G.K. Butterfield in North Carolina, as well as the departures of Reps. Charlie Crist in Florida, Conor Lamb in Pennsylvania and Tim Ryan in Ohio — who are all seeking higher office.

That’s not counting one of the party’s biggest mysteries: the future of its House leaders. None of the so-called “big three” — Speaker Nancy Pelosi, House Majority Leader Steny Hoyer and House Majority Whip Jim Clyburn — have revealed their plans for 2022, although Pelosi has previously said this would be her last term.

The last bows by members like DeFazio or Yarmuth, who represent blue districts, further enforce the increasingly entrenched narrative that Democrats won't be able to overcome the headwinds threatening their House majority. And after they worked painstakingly to pass two massive bills, there’s a sense that the next cycle’s agenda will be more modest regardless of who holds power.

“I mean, 2023 is not going to be as exciting as what we're doing now,” Rep. Brad Sherman (D-Calif.) said. "Even if we're still in the majority.”
