The potential Millennial electorate gets bigger every year, and will keep getting bigger until about 2025. Contemporary politicians don't really understand the Millennial Generation; they package their ideology as if America were still in the 1990s except to recognize that the GI Generation is no longer relevant.
Millennial politics begins as it does in all political generations -- locally and well out of the limelight. They are approaching the mid-30s... and one might expect some Millennial pols to offer at the least new language about concerns largely neglected today. It won't be Culture Wars.
Millennial pols will do what other generations have done: they will fill gaps.
The greatest evil is not now done in those sordid "dens of crime" (or) even in concentration camps and labour camps. In those we see its final result. But it is conceived and ordered... in clean, carpeted, warmed and well-lighted offices, by (those) who do not need to raise their voices. Hence, naturally enough, my symbol for Hell is something like the bureaucracy of a police state or the office of a thoroughly nasty business concern."
― C.S. Lewis, The Screwtape Letters
