Democrats' big 2026 midterm wins, after many campaigned against data centers, are prompting party leaders to call for restrictions on the AI build-out, with Sen. Bernie Sanders writing "National data center moratorium now" and Rep. Yassamin Ansari urging a pause on AI development as a Day 1 priority. AI-linked stocks fell after the election, with chip stocks leading — Nvidia down 8% and the iShares Semiconductor ETF tumbling nearly 9% — as investors worried the Democratic wins could affect data center construction.
