Senate leaders face scrutiny after Democrats' decisive election win

Senators returned to Washington Monday facing leadership questions after last week's election gave Democrats a significant new Senate majority, with Republicans debating John Thune's reelection and Democrats privately questioning Chuck Schumer's role. Republicans, losing about a quarter of their conference, will vote Tuesday on Thune, though some seek a delay until Alaska and Mississippi races conclude. Democrats, potentially holding 56 seats, may see Maryland Sen. Chris Van Hollen challenge Schumer, who led the party to historic wins. Both leaders are expected to win their secret-ballot votes, with Republicans voting this week and Democrats likely in December. The internal debates could shape party effectiveness in the next Congress and perceptions ahead of the 2028 presidential election.
