  • Corrected Hickenlooper's Denver mayoral years from 2004-2010 to 2003-2011 in both the summary and background (Ballotpedia's own bio text, and known public record, place his mayoralty at 2003-2011, though Ballotpedia's infobox mismatches the body text) to match the source's stated years and be consistent with governor years 2011-2019.
  • Fixed capitalization of Hickenlooper immigration quote ('Enforcement' to 'enforcement') to match the exact source wording.
