Spanish prime minister Sanchez said US voters rejected policies that would only produce poverty, and rejected hate, gender discrimination, climate denial and elite privilege. He said the same dynamic occurred in Brazil, has just reappeared in the United States, and will soon occur in Spain.

Democrats have won six of seven competitive swing states — Texas, Kansas, Ohio, Iowa, Maine and Michigan — in the final phase of the midterms. Texas has not elected a Democratic federal senator since 1988 and Kansas since 1932; both results are major upsets. Ohio, a state previously represented in the Senate by Vance, also failed to reverse Republican losses. Democrats additionally flipped North Carolina and South Carolina, totaling seven pickups, and are projected to hold 54 Senate seats. Alaska remains undecided amid a same-name candidate dispute.

At a Nov. 4 press briefing, China’s Foreign Ministry responded to a Nov. 3 UK National Cyber Security Centre annual report saying China, as a major AI power, is "very likely" to frequently use AI for hacking by 2028 and would represent the UK's most complex, persistent cyber threat. China said it had noted the report and voiced serious concern that the UK was smearing China with speculative claims without evidence. It called AI-related cyber risks a shared global challenge best addressed through new UN rules, accused the UK of politicizing cybersecurity and using hacking allegations to suppress China’s AI development—actions it said would damage bilateral trust and the UK’s credibility in global AI governance. China reiterated that AI development should be upward-looking, open and inclusive, and that security and development must be balanced to ensure AI is safe, reliable and controllable.
