If you follow politics, you know that California is a solidly blue state. But, it wasn't always so. In fact, in the six presidential elections between 1968 and 1988, the Republican presidential nominee carried the Golden State every single time.
How states evolved in their politics and voting patterns is of endless fascination to us political nerds at the Fix. Now, thanks to the chart below, which was designed by Riverbed Design and posted online by AIGA Seattle, you can trace how each state voted in every election since 1796. (Yes, 1796!)
This is terrific stuff. Prepare to lose some of your afternoon following your state (or states) over time. And, click on the chart for a large image.
