Colorado is a lot more moderate economically where as California is more liberal.
In case you haven't noticed, D=moderate economically.
In Colorado I'm sure the D's are moderate there economically but California they are liberal on economic issues. California is like 44th in job creation per Gallup "State of the States" stats and is 48th on Business Climate per the "Tax Foundation". Colorado is 18th in Business Climate per the "Tax Foundation". Don't have job creation stats off-hand for CO though.
Not many California residents are "liberal on economic issues". Gg.
