In the old days of smoke filled rooms, power had secrets and wealth kept guarded counsel, working behind closed doors to ever augment its privileges. In the age of the internet, there are fewer secrets. Few are needed. Power can still satisfy itself as if unobserved because it holds one last secret: A population with a remote control in one hand and a beer in the other just won't jeopardize its ease to enquire what moves the movers make or whom the shakers shake.
A government that schemes to prevent the votes of some people is not government of the people, by the people or for the people and will take many down with it when it perishes.
Majority and minority should both be outraged for it is only cleanly working democracy that makes those demographics mean anything or have any hope of trading places from time to time.
