If Democrats win back Congress, as forecasts suggest they will, the effects will reach well beyond Washington, and a power shift could make life harder for tech leaders who have bet heavily on the current political order, according to the article. A change of control on Capitol Hill usually means more hearings, more document requests and more questions, and for industries still waiting on clear rules, such as AI and crypto, it also means a regulatory picture that is harder to predict. The article cites Nvidia boss Jensen Huang, who has cultivated a close tie to Trump while lobbying on AI policy, especially to keep the right to sell chips to China, and notes that Sen. Elizabeth Warren has already taken a shot at what she calls his “backroom” dealings with the president. It also cites Zuckerberg, who has built a warm relationship with Trump, which has helped Meta handle scrutiny over its AI work, and states that with the Democrats controlling the Congress, Zuckerberg's AI ambitions may face a roadblock. The article adds that even if Democrats win both chambers, Yardeni says, they may have little power to rein Trump in, and while he stays in the White House, the business leaders close to him still have some protection.
