Candidates are trying to earn the majority vote, not your vote specifically. Democracy is largely about compromise. It’s not about convincing people that you’re right, but about serving the majority. Your issue here is with the majority of voters, not the people seeking their votes.
Re the first point, that’s an issue with your system of democracy, (I agree that it’s stupid and outdated) again not an issue with Hilary herself.
I’m afraid I have to disagree with your second point, I think we fundamentally disagree on what democracy is. Electees are there to serve the people who vote them in, if the minority of those people want change then they need to convince the electorate, not the candidates.
For context, I think we probably align quite closely politically, I just feel your expectations are misplaced.
