Republicans have decisively won the majority in the U.S. House of Representatives, meaning that House Speaker Nancy Pelosi is out of a job and will have to hand over that title to a Republican.
California Representative Kevin McCarthy may or may not take on that role. He has to be elected by his party to do so. McCarthy has signaled less support for extending the war in Ukraine, but his loyalty to the Trump-era Republicans may be in question. He will have to fight for the votes to take on the job in January.
Democrats retained a majority in the Senate so the three partisan branches of government will be divided as such in the new year: Executive: Democratic, House of Representatives: Republican, Senate: Democratic. The judicial branch, meaning the Supreme Court also skews Republican.
