Overview
- Major networks projected on Tuesday night that Democrats will control both the House and the Senate, flipping multiple Republican seats and reshaping Capitol Hill's balance of power.
- Exit polling and reporting show the Iran military campaign and its effect on fuel and living costs were leading reasons voters defected from Republican candidates.
- President Donald Trump and Vice President JD Vance publicly acknowledged the war hurt Republican performance, and Iran’s parliamentary speaker framed the outcome as a rejection of war.
- With committee chairs and appropriations leverage, Democrats are preparing oversight actions, subpoenas and possible legislative moves to restrict funding for the Iran conflict and probe administration decisions.
- Heavy spending by tech billionaires to support Republicans drew sharp voter backlash, helping Democrats win key races in states such as Texas and elevating local concerns about the energy and cost impacts of AI data‑centre projects.
