Over a couple of decades of trying to encourage registration and voting among communities living at the margins -- people of color, queers, young people -- I have given training after training in which I've claimed: "voting is learned behavior. If you can persuade people to try participating, they'll likely continue to use this tool, among many, in their struggles to empower their communities."
Incidental to understanding its own polling in this endless election, Survey Monkey has offered this graphic representation of their findings about how committed various potential voters were to their choice of candidate in mid-August.
I'm not thrilled with the voting habits of many old white voters who reliably keep choosing Republicans. But there are many young people and newcomers who need get started on the habit of making the best choice available; get 'em started and results change.
