Yes, they absolutely are. If they didn't like it, they would fight to have it changed. They've fought to have many other things changed, and various Constitutional Amendments have been passed as a result. Did you forget the 18th Amendment, which was passed because of a bunch of Temperance activists? (and then the 21st that was passed because the result was a disaster) The system is set up this way because the voters don't want to change it.
