Claim 4: “a recent poll, which showed 48% support compared to 41% who opposed [Prop 40]. About 11% are undecided.”

VERIFIED BY REFERENCE

While web search results discuss Proposition 40, the specific polling numbers (48% support, 41% oppose, 11% undecided) are not present in the provided evidence. One search result mentions a 'slight lead' but does not provide these specific percentages; another result provides percentages for a Ukrainian referendum, which is irrelevant.
