The holiday season is powered by eggnog, tinsel, the time-honored tradition of fighting with those closest to you -- and deep denial of those family rifts.

Democrats President Obama and House Minority Leader Nancy Pelosi -- who attended the White House Christmas party earlier this week -- were in full holiday mode Thursday, with a rare (and significant) public disagreement on whether the House should pass a $1.1 trillion spending package.

Pelosi (D-Calif.) said she would not support the bill because it would undo parts of the Dodd-Frank financial regulatory overhaul. And she accused the White House of bending to "blackmail" by letting the provision that would gut the reform into the bill.

"I’m enormously disappointed that the White House feels that the only way they can get a bill is to go along with this," Pelosi said on the House floor, in a rare public split with the administration. The House narrowly passed the bill Thursday night.

Of course, no holiday disagreement would be truly complete without a dose of denial.

On Friday, Earnest said the relationship between Obama and Pelosi is not strained. Not strained at all.

"It’s hard to think of anybody that the president has worked with more closely or more successfully on Capitol Hill than Leader Pelosi," Earnest said, adding that none of Obama's domestic legislative achievements would have been possible without Pelosi. 

Of course, this time around it was Obama and his longtime foe, House Majority Leader John Boehner (R-Ohio) both working to support the bill, along with Senate Majority Leader Harry Reid (D-Nev.). Pelosi was on the sidelines

It's the latest example of an intra-party gap that's been widening in the past month.

"The rift among the Democrats, which has grown wider since the party got beaten badly on Election Day, has left Obama and his would-be allies on the Hill increasingly pointing fingers at one another: Senate Democrats blame Obama for costing them their majority; White House officials blame them right back; and when the two sides agree, the populists in the Senate and House step in and try to blow it all up," according to our colleague Paul Kane.

In other words: for Democrats, the season's been just a bit less jolly this year. Of course, that's not the line from the podium.

"I continue to be confident, and I know that the president is confident, that the strong working relationship and the effective, productive working relationship that we’ve had over the last six years will continue for the next two," Earnest said.
