Yes, however those people also have right to vote (in democracies) and many of them vote without being sure what they vote for. Democracies can be hacked because too many people are either not interested or not informed well enough to vote for what's really best for them and the country.
Why would they participate in system that they don't believe? Also, you need to be populist to win in democracy, which brings another pathological behavior into game by definition of system.
