Colorado gained statehood in August 1876. After voting primarily Republican from 1920-2004, the state has voted with the Democrats in the last four presidential elections, including Joe Biden's 13.5% margin in 2020. That marked the first double-digit Democratic margin here since Lyndon Johnson won by 23% over Barry Goldwater in 1964.
In recent decades, Coloradoâs population has been growing more quickly than that of the country. This has led to a corresponding increase in electoral votes, from six as recently as 1968 to 10 as of 2024.
