Reynolds wiped out the old really rotten minority rule gerrymanders.
The current *regime* is now circa 25-30 percent indirect minority rule --- a
plurality of the votes in a bare majority of the districts for partisan
indirect minority rule -- ALL State legislatures in the U.S.A and the U.S.A.
House of Representatives.
The U.S.A. Senate gerrymander (2 Senators per State regardless of anything
else- number of voters, number of census folks, etc.) is a classic
semi-permanent gerrymander.
Thus, the major pressure on this list for proportional representation to save
Democracy in the U.S.A. before the various de facto oligarchies in such
legislative bodies (compounded by monarchist thinking in the brains of U.S.A.
Presidents and State governors) cause some very major problems.
