Republicans’ dreams of a productive lame-duck session are dimming. Members returning to Washington post-election will have a mere 24 legislative days to get through a considerable list of must-pass bills and possibly messy internal leadership fights. That’s if they can overcome a potential transition of power on Capitol Hill and a foul national mood.

Lawmakers’ must-do list includes: an extension of government funding past Dec. 11 and the annual Pentagon policy bill. Major legislation to reauthorize farm, transportation and surveillance programs are also on deck. Then there are pending bipartisan bills overhauling energy permitting and the college sports industry that many members are itching to get done. And finally, leaders had deferred some GOP priorities — such as another party-line reconciliation bill or debt-limit increase through the end of President Donald Trump’s term.

All of the measures face their own potential political minefields individually, as well as a number of obstacles across the board: — ATTENDANCE: There will be little incentive for lawmakers who just lost their seats — “free-range chickens,” some call them — to grind out legislative wins, if they come back at all. “The question becomes: Who shows up for work after the elections?”Rep. Austin Scott said in an interview.

“Attendance is an issue right now.” — NEW LEVERAGE: If Democrats win control of either chamber, they’ll likely seek greater influence on legislation to push back on Trump’s actions. For example, Democrats are fuming over the Trump administration’s recent decision to block roughly $1 billion in congressionally approved funding, which could complicate any deal on spending legislation. They’ve also blocked the annual Pentagon policy bill amid a standoff over the Iran war; and they may push for more concessions on the permitting deal. “The lame duck will be quite different if we win the Senate,” Minority Leader Chuck Schumer said in a recent interview. — GOP DISPUTES: While some Republicans believe that losing a chamber would jump-start the reconciliation process, others privately believe the exact opposite would happen, with incentives waning for exiting lawmakers, according to three GOP aides granted anonymity to speak candidly. Other GOP senators, like Sen. Cynthia Lummis, are skeptical of a debt-limit increase.

A Democratic flip of the House could also spark a potentially chaotic cascade of GOP leadership elections (more on that below).

Sen. John Kennedy speculated Congress’ agenda would all come down to the vibes of the GOP conference when they returned. “You have no idea what the mood is going to be,” Kennedy said.

What else we’re watching: — JOHNSON SCRAMBLES LEADERSHIP OUTLOOK: Republicans are reassessing the dynamics of potential leadership races after Speaker Mike Johnson‘s comments Monday that he would run for minority leader if the GOP loses the House — just days after he floated leaving Congress altogether in that scenario. Many Republicans had predicted Johnson would step aside with a House flip, likely setting off a race between Majority Leader Steve Scalise and Judiciary Chair Jim Jordan for the top GOP spot.

If Johnson stays put, his success may depend on the severity of the party’s loss and if Trump weighs in for a certain candidate. “I hope he’s smarter than that,” one House Republican said of Johnson’s consideration of the minority leader role.

“It would end very badly and cause unnecessary damage to the conference.” — DEMS GEAR UP ON TRADE OVERSIGHT — Democrats on the House Ways and Means, Senate Finance and other panels say Trump’s trade deals were corrupt, and they’re already lining up targets to probe.

The party knows it can’t repeal Trump’s tariffs as long as he’s in the White House, but if they win control of Congress, they plan to haul in top administration officials and possibly executives to explain how Trump picked his targets in his trade war — and if others got a pass through suspected quid pro quos.
