Except that that is how American government works, and always has. We're not a democracy, we're a representative republic, and we expect that our representatives will do what is right for all citizens, regardless of what the majority of citizens want or believe, to prevent "The Tyranny of the Majority".
Nearly every major advance in human rights in this country had to be imposed by the government, and it was actively fought against (and much of it still is) by a huge percentage of the population. That's then entire reason for the Secession of the Confederate States, after all. If it had been left to a majority vote, slavery would have remained the law of the land for many, many decades longer than it did, and Jim Crow laws never would have been repealed in the overwhelming number states that enacted them. Hell, there a whole lot of people in bit parts of this country who are trying to return us to those days.
In this particular case, quotas for politician's doesn't make the slightest bit of sense, but government overriding the will of the majority most certainly does.
Except, again, America is not actually a democracy, never has been, and there is a very good reason for that.
