  A new Institute for Strategic Dialogue study put six popular chatbots through 2,400 election questions and found 29% of English answers were incomplete, outdated or wrong enough to potentially mislead a voter.

• Overall accuracy dropped from 71% in English to 55% in Spanish — researchers say the gap comes mostly from missing details, not flat-out factual errors.
• OpenAI's GPT-5.5 held up best in both languages; four of the six chatbots — including Meta's Muse Spark and Anthropic's Sonnet 4.6 — answered fewer than 60% of Spanish prompts correctly.

Two months before the midterms, a growing share of voters are typing election questions into a chatbot instead of a browser — and a new study suggests the answer they get back shouldn't be taken at face value, especially if they're asking in Spanish.
