I know exactly what you mean and I have felt that way for quite a while now.
I refuse to support any candidate, even the local dog catcher if they are not prepared to represent everyone they are being elected to represent. I find it absolutely appalling that a presidential candidate and former president would openly attack any part of the population he will be elected to serve.
Our biggest problem is that there is no accountability, so corruption is rampant throughout the entire system. There was a political party a while back that had a solution. The party was aimed at putting representation back into Congress. The party was called GOOOH (Get Out Of Our House).
The plan was to elect local citizens (not lawyers, politicians, or millionaires) at the local level. With a sort of round-robin convention, those with the highest vote count moved up to the next level until there were enough people to fill any vacancies in Congress.
The catch is that every candidate must fill out a 100+-question survey about how they will vote on a given issue. That becomes a binding contract. If they get into office, they are prohibited from voting in any way contrary to that contract. Violation means they are removed from office immediately and the next candidate replaces them.
If a situation arises, such as new information is available that would cause the representative to vote contrary to their contract, they must first go back to the citizens and explain why. If the citizens agree, the rep can change their vote. If the citizens disagree, the candidate is bound to vote according to the will of the people.
Notice that there is no PAC money involved. Votes would no longer bought with donations or gifts. It removes money from the equation.
The party was gaining momentum because this is what people really want. However, the existing parties shut them down because they have a sweet deal, making politicians millionaires with dirty money.
As Murphy's Law states, "Reform always comes from below. The player with four aces never asks for a new deal."
The website is now shut down, but Wikipedia has an article explaining how it worked.
