Example: I usually do not vote in the party primaries in my state, because the party that primary voters selected is public. Mostly, I don't want to get tagged by Big Data as having a political affiliation. These combine with "at will" employment such that I could be fired for voting in the "wrong" primary for my company, with no laws broken. I'm not saying it has ever happened, but it could. Murphy's Law provides the rest. In the general election, the only public information is whether I voted or not. So I vote as I please. I can still be fired for wearing only the minimum required amount of flair, but at least that's not interfering with democracy. Public votes can also be sold. If you say you'll pay me $X if I vote for Y, making the Y vote public means they buyer can know that they got what they paid for.
