The 90+ something percentage of the world's population already have a mountain to climb trying to meet their own basic needs (food, shelter, clothing, health care) and work a full time job (if not two) as a way to financially support themselves towards those needs.
They might give an opinion about a candidate or a social/political issue here and there but unless he/she has aspirations of a career in politics, they probably won't care much unless it deals with a topic that directly affects their livelihood.
