People lack an assigned identity these days. We don't have tribes or clans, our families are not close, we live the same way as millions of others around us, and in our highly individualistic society many of us are not even on a team trying to accomplish anything together (no your department at work doesn't count).
So we buy our identities off the shelf through sports fandom, fashion labels, status symbols, and, yes, politics. Politics are a consumer product.
Political ideologies offer a comforting sense of belonging, energize people with a sense of purpose, resolve anxiety-provoking uncertainty and moral self-questioning, etc. All these product benefits can be yours for the low low price of conformity. May relieve symptoms of depression and existential angst.
Unfortunately, the most successful ideologies blame some demographic (minorities or "the 1%") for all their constituents' dissatisfactions with life. This is because the people most likely to buy one of these products are the type who have already failed to take accountability for themselves.
That is not an excuse to leave something as powerful as government in such hands. Vote every time!!!
