Democrats are increasingly concerned that they will narrowly lose the House of Representatives following Republican victories in the Senate and White House.

The balance of power in the House is expected to become razor-thin no matter who wins, but sources who spoke to Fox News Digital fear the Democrats' path is narrowing.

“We will almost certainly lose the House by a narrow margin,” a senior House Democratic aide told Fox News Digital. “We got a kick in the ass.”

However, the House aide was optimistic about the Republicans' comparatively decisive victories in the upper house and in the presidential election campaign.

“If you told me that (President-elect Trump) could win the popular vote, dominate the Electoral College and end up with 56 seats in the Senate, the House map really wouldn’t be bad,” they said.

A person familiar with House Democrats' campaigns told Fox News Digital: “If there's any indication last night about how the House is going to go, I'm not confident. The American people are clearly not buying what we are selling.”

“Honestly, I think it depends on the economy,” the second source said. “People feel like they can have more in their bank account.”

As of early Wednesday afternoon, Republicans were ahead of Democrats by nearly two dozen projected wins, according to the Associated Press.

The winning party must complete 218 of 435 House races to control the chamber, and there are those on the Democratic side who still hold out hope, but recognizing the margins would be tenuous.

“I think Democrats are still hopeful … there's a chance to make a few twists and turns to get a narrow majority,” longtime Democratic strategist Joel Rubin told Fox News Digital.

Rubin pointed to uncontested seats in California and New York currently held by Republican incumbents, as well as an open seat in Maryland that Democrats are fighting to retain.

House Minority Leader Hakeem Jeffries from New York also remained hopeful on Wednesday afternoon.

“The House remains very much in play due to the continued strength of our battle-tested incumbents, critical open seats in Virginia and Michigan, victories in Alabama and Louisiana, and the flipping of four Republican-held seats in New York this year. “Jeffries said in a statement.

“The path to reclaiming the majority now runs through narrow margins in Arizona, Oregon and Iowa – along with several Democratic-leaning counties in Southern California and the Central Valley.”

Jeffries, who is likely to become House speaker if Democrats win, vowed that his group would “continue to govern with common sense and conviction.”

In their quest to win the majority, Democrats are poised to unseat two Republican incumbents – New York Reps. Marc Molinaro and Brandon Williams.

Meanwhile, Republicans are expected to take control of the open Michigan seat vacated by Democratic Rep. Elissa Slotkin. Reps. Matt Cartwright and Susan Wild, vulnerable Democrats in Pennsylvania, left their races to their respective Republican challengers.

At the presidential level, Democrats – including those in the House of Representatives – have already started pointing fingers.

Representative Ritchie Torres, a pragmatic Democrat from New York, blamed the “far left” for the loss of Vice President Kamala Harris.

“Donald Trump has no greater friend than the far left, which has achieved historic numbers of Latinos, Blacks with absurdities like 'Defund the Police' or 'From the River to the Sea' or 'From the River to the Sea.' “Latinx,” Torres wrote on X, to alienate Asians and Jews from the Democratic Party.

“The working class doesn’t buy the ivory tower nonsense that the far left sells.”
