Although Colorado remains competitive between the two main political parties, with candidates representing both parties winning statewide races and splitting control of the state legislature, the state has, in fact, moved at least two points to the Democratic side of the scale since 2006. This is most clearly shown in terms of registration and voter behavior in presidential elections. Republicans have lost their registration advantage. Voters not affiliated with a party are now the largest political group in the state, and polling shows that they skew younger and somewhat more liberal and Democratic. The presidential races since 1996 offer evidence that Colorado has shifted to the Democratic side with Barack Obama’s elections, and has remained in that camp through Hillary Clinton’s win in the state during the 2016 presidential election.
