Visualizing Changes in the Balance of the Two Party Vote

As a big fan of cartograms I find the video below fascinating. This video uses isarithmic mapping to showcase the shift in the two-party vote in the US over the past 90 years. When the historical red-blue political balance is shown visually I'm reminded that despite how deeply entrenched our current political state feels the winds of political favor do shift quickly and dramatically.

How do you think this map will look 30 years from now?
