Correction: The only voters who have a voice in government are the ones who win!
Wrong. How much political capital does a politician spend on voter groups who are going to vote for his reelection no matter what he does? That's the reason GOP pols govern left of their constituents, they are trying to recruit voters they don't already own.
When you find the politician that agrees with 'you' 100% *AND* he can win, let me know. Until then YOU are going to be on the outside looking in.
Politics is the 'art of the compromise', you haven't figured that out yet.
