The idea that no voters changed from blue to red is nuts. 10 million (so far) less votes over all don’t mean the same people:

1. Where alive this time
2. Voted the same
3. Voted at all

The idea that it is “low-information” voters is also suspect as the race was between Trump (who I doubt any US citizen has NOT heard of) and the status quo. They might have just not seen a compelling reason to vote, a thing that people can chose to do.

You can place blame on people staying home, but in my opinion if the DNC exists in four years (in even slightly the way it is now) you will have more people sitting it out next time (if there is one). We are watching the inevitable end to any two party political system.
