All political systems get hacked. If you understood your nation’s history you would understand that its coming into existence was the result of a hack. You are too focused on the technology used today. Every 4th of July you celebrate the men that committed the first hack of the system and even they expected their newly created system subject to continuous hacking.
The real question is why would anyone attempt to hack a political system unless they believed the allocation of “justice” was not sufficient? Politics is about allocation of power. Whether the hackers are a bunch of slave-holding white boys in 1776, black and Jewish civil rights leaders in 1963, women’s lib protesters in 1972, or white nationalists in 2017, someone or some group is always hacking your system.
Maybe you should take a closer look at your system. It’s like driving a car that breaks down every ten miles. Sooner or later you have to figure out why.
