Colorado

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.

Colorado’s population has been growing, and it now has 50% more electoral votes than it did in the 1960s. Based on population trends, the state is likely to gain a 10th electoral vote after the 2020 Census is released.
