One of the 3 branches of our federal government is a "polit-bureau of 9" and it functions better than the other two. Our elections are frequent which forces politicians to continually give away free stuff and special favors at taxpayers expense. Every election we go more broke. Public elections are nice in theory but they don't work for long in practice. When the USA was founded, elections were limited to men that owned land, a workable design. What we have now is nothing close to that.
One of the reasons the Judicial branch doesn't appear to be a "dysfunctional" as you believe the others to be is that they are pretty much sequestered from the daily political give-and-take wrangling that goes into making law. If they were to simply pronounce the law they would be dictators and the will of the people would be ignored.
I also disagree that it is a particularly conservative court at this point. With so many 5-4 decisions on crucial rulings I think it is a split court becoming more liberal all the time. One more liberal voice on that court and it would become a liberal voice of dictatorship.
You are calling for tyranny. In no way can I or true conservatives support it.
