Actually, the "right" of 'everyman' to vote, no matter their contribution to society, therefore enabling the ability to divide by those seeking to further political power/agendas, and to then pander to those divisions for political gain, was the very first, albeit subtle, nail in the coffin of our democratic republic.
You can gasp, rail, gnash your teeth, and cry foul over the obvious result of a supposed cherished belief, but history is proving it to be so ... and that one tweaking of what the founders originally set up will continue to preside over the rapid diminishing of a once unique democratic republic.
