President-elect Donald Trump scored a major victory last month by carrying the popular vote as well as winning 312 votes in the Electoral College.

Yet House Republicans had a far less impressive showing, meaning that the removal of even a few GOP representatives could leave Trump scrambling.  

Republicans lose California seat

That fact was pointed out by the New York Post on Wednesday, which noted how the final House race was called earlier this week.

In that contest, Republican Rep. John Duarte found himself being ousted by Democratic challenger Adam Gray in California's 13th District.

Duarte loss means that Republicans now hold just 220 House seats compared with 215 that are occupied by Democrats. What's more, the Post noted that another three GOP members are slated to leave in January.

House Speaker Mike Johnson acknowledged on Wednesday that his party will face challenges given its razor-thin advantage.

Johnson: "We know how to work with a small majority"

"The House would have a larger majority but redistricting and gerrymandering in the blue states made that almost impossible to, but we do have a majority and we know how to govern with that small majority," the Post quoted Johnson as telling Fox News.

"We've been doing it for a year. We will fill those seats — there will be three vacant, so it will go from 220 to 217, that is razor-thin, but it will only be for a few months," he added.

The New York Times reported that Johnson reiterated that message earlier in the day when speaking with reporters on Capitol Hill.

"We know how to work with a small majority. That’s our custom," the Louisiana lawmaker said of his caucus' diminutive size.

"We have nothing to spare. But all of our members know that. We talked about that today, as we do constantly — that this is a team effort, that we’ve got to all row in the same direction," Johnson insisted.

Two members of Congress expected to serve in Trump's administration

Among those leaving are New York Republican Rep. Elise Stefanik and Florida Republican Rep. Mike Waltz. Trump nominated Stefanik to become United Nations ambassador while Waltz has been selected as National Security Adviser.

Meanwhile, former Florida Republican Rep. Matt Gaetz resigned his seat last month after being nominated to serve as attorney general. Gaetz subsequently withdrew his nomination.

The Post stressed that depending on when Stefanik and Waltz depart, Johnson could be left presiding over the smallest House majority in American history.
