Welcome to From the Politics Desk , a daily newsletter that brings you the NBC News Politics team’s latest reporting and analysis from the White House, Capitol Hill and the campaign trail.

In today’s edition, Sahil Kapur digs into the vibe shift on Capitol Hill with lawmakers returning to Washington for the first time since the midterm elections. Plus, Joelle Gross zeroes in on the Democratic candidates who made the furthest inroads with President Donald Trump’s voters.

The vibes are different on Capitol Hill, with Republicans still shell-shocked by the magnitude of last week’s electoral thumping as they return to Washington as lame ducks with a lengthy to-do list .

Democrats feel empowered by their far-reaching midterm victories, as they made deep incursions into red-leaning territory amid a voter backlash to Trump.

Some say that their mandate includes ending the Iran war and that lawmakers shouldn’t pass any government funding bill without cutting off money for Trump to continue the war without congressional approval.

“I believe we would abdicate our responsibility if we voted to provide billions of additional dollars for President Trump’s war of choice in Iran,” Sen. Michael Bennet , D-Colo., a moderate, wrote in a letter to colleagues Saturday. “We must refuse to invoke cloture on any package that includes another cent for his war.”

Meanwhile, a small group of Republicans is pushing to delay tomorrow’s closed-door meeting to pick their leadership team for the next two years. The top three GOP senators — John Thune of South Dakota, John Barrasso of Wyoming and Tom Cotton of Arkansas — are favored to hold their positions in the minority, but not without some pushback.

“A week ago, we had the worst election result in decades. We need a discussion about what went wrong, how we fix it, what we stand for, and how our agenda must focus on the concerns of the American people,” Sen. David McCormick , R-Pa., who rarely steps out of line with GOP leadership, said in a statement.

“As I’ve shared with Leader Thune, I don’t believe we should move to leadership elections until we have digested and debated the lessons of the midterms and how to move forward,” he added.

There is no internal consensus yet among Republicans about why they lost so decisively, and many of them are reluctant to point fingers at Trump, even though the results and exit polls overwhelmingly indicate voters were delivering a rebuke of him.

Thune said the election gives the GOP an “opportunity to reflect on what we as a party need to do better.”

The big question for Trump and Republicans is how much they’re willing to compromise over the next six weeks, while they retain their maximum leverage, to achieve some of their year-end goals. Come Jan. 3, Democrats are poised to take power on Capitol Hill with some of the biggest majorities here since 2009.

Millions of Americans who voted for President Donald Trump backed Democrats in last week’s midterm elections — that much is clear from the vote counts. But to understand why, it helps to drill down into the exit polls.

Voters turned away from Trump and the Republicans out of deep frustration over the economy and concerns about the state of American democracy, an analysis of the NBC News Exit Poll data found. Democrats re-energized young and Latino voters, among other groups, fueling a historic takeover of Congress and grabbing Senate seats in states that had seemed tattooed red.

Tuesday’s Democratic success came not only by mobilizing the party’s base. Senate candidates from Texas to South Carolina to New Hampshire swayed former Trump voters. In some states, percentages of Trump voters turning out for Democrats reached double digits.

About 13% of voters who chose Trump in 2024 voted for Democratic Sen. Jon Ossoff in Georgia this year, the exit poll suggests. James Talarico in Texas and Mark Warner in Virginia drew 11%. Nationally, around 7% of former Trump voters opted for Democratic candidates in House elections. By comparison, 2% of those who voted for Kamala Harris split for Republican House candidates.
