How to read it. Left of the centre line: the state voted more Republican than the country that year. Right: more Democratic. A highlighted line's colour is the side the state was on in the latest election shown. Washington, D.C., which voted sixty-four to ninety-one points more Democratic than the nation, is off the scale and left out.
