Zen, I think you figured it out.

After the midterm elections, I recall Obama saying he was listening to the one third who voted as well as the two thirds who did not vote.
A couple of days later I saw an editorial cartoon of Obama peering into a crystal ball, asking those who did not vote what they were thinking.

Gee that seams to work ok in North Korea and everybody votes for Kin Jong Un. Wow isn't that how "O" would want it.

Would the requirement extend to illegals and dead people??? Would Chicago be required to put a maximum number of times one person can vote? So many questions...

Just use Hillary's email server farm for notice, and the banks will gladly remove the penalty fees from accounts (and keep it for themselves of course.)

And as for me, give me liberty from voting or give me successful revolution.

Government in general might not want to tug too hard on that particular thread. Politicians might wake up to find a ballot initiative to institute all kinds of changes like, say, a requirement that all ballots must have a new, additional choice on them. One that says, "None of the above". Transformative he says? Indeed.

The government will vote for you if you don't do it yourself based on the formula: V= |O<=p(D)/p(R)<=1|. Of course, the DOJ will determine what numbers to plug into the formula.

Let's see....28 million v. 316 million.
A driver we hired in Oz told us his son just turned 18 and he got a letter saying you will now vote or pay $150.
But again it's 28 v 316 million

So when they can make sure you voted, they can then make sure you vote the right way.
