Trump's anticipated endorsement remains the dominant factor shaping trader consensus in the Senate Republican leadership race, where John Thune holds a strong lead in internal GOP senator surveys over John Cornyn and others after Tim Scott's withdrawal. Recent private meetings between Trump and the contenders at Mar-a-Lago have heightened anticipation, but the president-elect has held off on a public nod, emphasizing his desire for loyalty amid fiscal hawk pressures. Traders price Thune's edge from incumbency and endorsements like McConnell's, yet a Trump-backed alternative could swiftly shift odds. The GOP conference vote, slated for early January 2025, looms as the pivotal event.
