Colorado used to be very polarized, but that's not so true anymore. It leans pretty strongly blue now:

> Biden won Colorado with over 55% of the vote, and by a victory margin of 13.50%, an 8.6 percentage point improvement on Clinton's victory in the state four years prior, the strongest Democratic performance since Lyndon B. Johnson in 1964, and the first time that it voted for a presidential candidate of either major party by a double-digit percentage since Ronald Reagan in 1984.

> In this election, Colorado weighed in as 9.1% more Democratic than the nation as a whole. The results established Colorado as a Democratic stronghold, rather than the Democratic-leaning battleground state it had been for the past three election cycles.
