Colorado had just shy of 87% voter turnout. Without getting into specifics that points to a state which is pretty easy to vote in (mail in ballots, easy access to ballot boxes, same day registation, etc.)

By contrast Georgia has historic minority voter turnout and voted in 2 democratic senators and voted for the democratic presidential candidate. In response the republican state government passed a law restricting voting under the claims of voter fraud despite there being no evidence showing such fraud.
