I see some candidates with core principles where I can predict they will stand tomorrow. You can nitpick about small details, but they have a consistent record.
Let's agree to disagree on that. I think that any professional, career politician, is consistent in that they serve their financial donors. That is where the frustration and anger of the voter emanates. It is not because that the average American voter thinks he/she is being ignored, it's because the average American voter knows he/she is being ignored.
