Again YES! The founders didn't believe the people had to earn the trust of the elected but the elected had to earn the trust of the people because it is our country and it doesn't matter what our elected representatives want.
On one hand you say that our system is based on the will of the representatives which says that people should have no say and then in the next sentence you say our votes for a representative should be based on who most "matches my own".
I'll try to make it simple:
It's impossible for a rep to know exactly what his districts "will" is. The system is designed so that people will vote for the person that matches them best, and whoever seems to match the most people in the district will win.
Then, that person is expected to vote their conscience (or wallet, as most seem to do now, since we don't ever vote out incumbents).
The catch in the system is the term - 2 years or 6. So, according to the design of our system, if a representative strays from the will of his or her constituents, they get voted out of office.
So if you're right, and such a huge number of people disagree with the health care plan, then they'll all get voted out next year.
But we both know that that won't happen. Incumbents win 90% of the time.
