Supermajority pairwise methods?

[DEMOREP1 at aol.com]

Currently there is around 30 percent indirect minority rule in all state
legislatures and in the U.S. House of Representatives .  (Each district
winner gets an average of  around 60 percent. A bare majority of the district
winners make/stop laws. Thus around 60 x 1/2 = around 30).

Getting a majority rule proportional representation legislature in every U.S.
State will be quite difficult enough.

Supermajorities permit, by definition, minority rule vetoes and can lead to a
major crisis.  Example- slavery in the U.S. might have been abolished
peacefully but for the existance of the U.S. Senate with its 1/3 plus 1
stopping any constitutional amendment.  Result- the 1861-1865 U.S. Civil War
with around 620,000 dead  (compared to the around 58,000 U.S. dead in the
1964-1975 Vietnam War).

Most constitutional limitations (those items restricting *mere* legislator
majorities such as Amendments 1-8 in the U.S. Constitution) exist because of
the tyrannical and generally deadly activities of past monarchies-
oligarchies (especially the pre-1776 extreme minority rule (rotten borough)
gerrymander in the British Parliament),
