It seems very hypocritical to think that people are responsible enough to choose their elected officials while at the same time argue that they can't be trusted to make an informed decision because of a Facebook ad which promised them what they wanted.

If you microtarget me and your opponent microtargets me, how am I going to be convinced by you? This is an adversarial process.

Problem: Politicians thrive on buying votes by targeting individual voters with tailored promises of government money spent in personally attractive ways.

Solution: Abolish the Welfare State, so there is nothing left to feed such promises.

Short of that, we shall have to accept the stench of special-interest politics rotting into individually targeted political ads, at all levels of government. At some point it is likely to turn totalitarian, because not only do you not control what "ads" you are fed but you also do not control what "news" you are fed -- and then you have no reliable, reasonable basis for any of your social, economical, or political actions.
