House Speaker Nancy Pelosi celebrated Joe Biden's election success, projecting that he'll win the presidency "momentarily," and addressed the unexpected losses Democrats suffered in the House.

"We lost some battles, but we won the war. We have the gavel," Pelosi said during a news conference Friday.

Pelosi said she was disappointed that Democrats didn't expand the majority in places like Texas, but she tried to focus on the bright spots of Biden on the cusp of winning the White House and maintaining power in at least one chamber of Congress.

"We held the House," Pelosi reiterated. She touted the quality of candidates who ran and said she hopes that Democrats who came up short would consider running again.

PELOSI FORMALLY ANNOUNCES HER RUN FOR HOUSE SPEAKER AGAIN, ASKS FOR SUPPORT

Pelosi's comments came as she announced her bid to run for House Speaker again as the House Democratic majority is shrinking and moderates are blaming the progressive agenda for their losses.

Pelosi was asked by Fox News' Chad Pergram Friday about the divisions among Democrats.

“There’s not tension in your caucus?” Pergram said.

“Welcome to my world ... I would say we have a difference of opinion in our caucus," she said.

Pelosi wrote each Democratic member a letter Thursday outlining the agenda for the next two years and asked for their support in reelecting her as speaker. She wrote confidently that Biden won the presidency, referring to working with "President-elect Joe Biden and Vice President-elect Kamala Harris."

"I am writing to request your support to be re-elected as Speaker," Pelosi wrote. "I do so with the utmost respect for the diverse viewpoints in our Democratic Caucus, the gravity of this role the urgency of the challenges ahead. I also do so with the great joy and appreciation to so many of you who have already offered your support."

Earning the speakership should be a tougher feat this year for Pelosi because the number of Democrats in her caucus is shrinking due to unexpected losses on Tuesday. Pelosi and Democrats were confident about expanding their majority by winning seats deep into President Trump territory, but instead moderate members from swing districts suffered losses. 

HOW PELOSI COULD FACE A ROCKY PATH TO THE SPEAKERSHIP NEXT YEAR

As of 2 p.m. Friday, seven Democrats lost their reelection bids, and no GOP incumbent had suffered defeat. Republicans picked up the seat of outgoing Libertarian Rep. Justin Amash in West Michigan, too.

Democrats netted two open seats in North Carolina thanks to new redrawn congressional maps. And Democrats flipped Georgia's 7th Congressional District held by retiring Rep. Rob Woodall, R-Ga. Democrat Carolyn Bourdeaux beat GOP candidate Rich McCormick in the suburban Atlanta district, the Associated Press called on Friday.

That means Democrats so far have a net loss of four seats in the House.

HOUSE OF CARDS? PELOSI MAY HAVE A HARD TIME BECOMING SPEAKER, GOP OFFICIALS SAY

The party breakdown currently stands at 211 for Democrats to 194 for Republicans with 30 races yet to be called. Republicans believe as the counting continues they'll flip more seats and their ranks could swell to 208 members and beyond.

On a Democratic caucus call Thursday afternoon, members vented frustration about the unexpected losses and some blamed progressive ideas like defunding the police, socialism and the Green New Deal as costing Democrats their seats in swing districts. 

Rep. Abigail Spanberger, D-Va., was particularly animated and lashed out at the leftward lean of the caucus, Fox News has confirmed. 

She told her colleagues: “We lost races we shouldn’t have lost. Defund the police almost cost me my race because of an attack ad. Don’t say socialism ever again. We need to get back to basics.” 

WHERE THINGS STAND IN THE HOUSE

Spanberger was among the 15 Democrats who did not support Pelosi two years ago for speaker. Pelosi could afford the defections because Democrats had such a strong majority after the 2018 midterm elections.

But this year will be different with the smaller numbers for Democrats.

Pelosi needs the majority of votes on the House floor to win the speakership. So if the House is 435 members, that's 218 votes.

Republicans, gleeful about their gains, have already predicted Pelosi is in trouble.

"I mean Nancy Pelosi doesn't even have a majority where she can be elected speaker again," Rep. Tom Emmer, R-Minn., chairman of the National Republican Congressional Committee, said Wednesday. "Whoever would have guessed that it'd be possible that Nancy Pelosi might not be the speaker?"

Pelosi on Friday acknowledged the "healthy" disagreements of her caucus and said she views the next term of Congress, with a Biden White House, as a chance to build consensus.

"President-elect Biden has a strong mandate to lead, and you'll have a strong Democratic House with him," Pelosi said.
