Both cited Chalkbeat Colorado sources are reachable and each documents the outcome for this promise with the quoted text appearing verbatim. (1) FULL-DAY KINDERGARTEN: The 2019 article confirms Polis signed HB19-1262 funding free full-day kindergarten statewide; the quote "Fulfilling a key campaign promise, Gov. Jared Polis on Tuesday signed into law a bill funding full-day kindergarten" is present verbatim, and the article shows him championing it as a top budget priority at a signing ceremony. (2) UNIVERSAL PRESCHOOL: The 2022 article confirms Polis signed HB22-1295 creating free universal preschool launching fall 2023; the quote "With this bill, families in Colorado with 4-year-olds will have access to free preschool in the fall of 2023, saving them money and preparing kids for success" is present verbatim and attributed to Polis, framed as a campaign promise he championed and delivered. LEADERSHIP: As governor Polis did not merely vote — he unveiled each policy as a flagship priority, funded them in his budget, drove them through the legislature, and signed them into law. This meets the CHAMPIONED (LED/DROVE) bar. Minor, transparently-disclosed caveat: statewide preschool provides ~15 free hours (universal access) rather than literally full-day for every child, but the pledge as framed was substantially achieved and Polis led it. Confidence slightly below the original 0.95 to reflect the full-day-preschool precision caveat; both leadership and delivery are otherwise solidly documented.
