Bannon is a populist, and America-first nationalist. Bannon is NOT a free-market reagonomics Republican. Remember, one of his criticisms of Obama was that he didn't bail out the auto-industry enough. This shouldn't be surprising who actually pays attention. There is also a large amount of Obama - Bernie - Trump voters, people need to get rid of simple Left vs Right thinking, there are multiple dimensions to politics.

The reason it is still red v blue, despite the more nuanced politics, is that in the end, those smaller groups majority, reliably vote for one party.

It is good to see independents growing as a group and the parties shrinking, it's trending towards 50% last I saw
