I liked your "young voter" paradigm for California vs. Wisconsin. There is a logical choice for young voters in both states, even if that vote goes differently in each state. .
But as a former young person, taking world events to this detail was not at the front of my mind. I always voted, but sometimes my vote was not so wise.
When I was 27, I joined a political party. Then my vote became rather partisan.
The fact that Mr. Trump is still a viable contender is a sign of a broken system. I have a suggestion to fix it----and it will require effort, but people are not interested.
Maybe they like the drama too much.
