Denver's Mayor Mike Johnston has launched a bid for the Democratic Party's 2028 national convention, highlighting his city's democratic values and ability to house homeless and decrease crime rates. He also highlighted Colorado's universal preschool and constitutional amendment protecting abortion access. The 2028 convention will mark 20 years since Denver hosted the convention and the party took control of Colorado's lawmaking process. Additionally, the city's infrastructure has improved since the 2008 convention, with new hotels, an improved 16th Street, a larger convention center and a more accessible rail line.
