Senator John Thune (R-SD) has been elected as the Senate Majority Leader, succeeding Mitch McConnell (R-KY), with mixed reactions among Republicans. Supporters of Donald Trump are cautious, fearing Thune may not fully support the MAGA agenda, while others see potential for him to effectively support Trump's policies. Meanwhile, Senator Tim Scott (R-SC) has been elected as the chairman of the National Republican Senatorial Committee (NRSC) and will lead the GOP's campaign efforts for the 2026 election cycle. He was elected uncontested, replacing Steve Daines (R-Mont.), and is focused on securing a Republican Senate with Trump's backing. Scott is a close ally of Trump, having campaigned vigorously with Senate GOP candidates and led significant fundraising efforts. The upcoming 2026 cycle poses challenges for Republicans with potential tough races, including those for GOP Senators Susan Collins and Thom Tillis.
