Their general concerns and frustrations are not at all without merit, and I personally agree with many of them. The problem is that the rank & file have been made to feel so desperate that they're willing to throw in with people who have clearly become ideologically radicalized. Bannon is a perfect example.
Identifying a problem and wanting to fix it is one thing.
The approach you choose to take to fix it is something else entirely.
I don't think the rank & file has an accurate grasp of the national carnage it's asking for. You can't govern via rage, paranoia and manipulation. Not successfully, anyway. Look to world history. It doesn't end well.
