The shift from a republic to a democracy

REPUBLIC:

Authority is derived through the election by the people
of public officials best fitted to represent them.
Attitude toward property is respect for laws and
individual rights, and a sensible economic procedure.
Attitude toward law is the administration of justice in
accord with fixed principles and established evidence,
with a strict regard to consequences.
A greater number of citizens and extent of
territory may be brought within its compass.
Avoids the dangerous extreme of either tyranny or mobocracy.
Results in statesmanship, liberty, reason, justice, contentment and progress.
Is the 'standard form' of government throughout the world.

A Republic is a form of government under a constitution which provides
for the election of (1) an executive and (2) a legislative body who,
working together in representative capacity, have all the power of
appointment, all power of legislation, all power to raise revenue and
appropriate expenditures and are required to create (3) a judiciary to
pass upon the justice and legality of their governmental acts and to
recognize (4) certain inherent unalienable rights.
Take away any one of those four elements and you are drifting into democracy."
