The next POTUS will nominate a Supreme Court judge. That is far, far more important than any local issue because Supreme Court decisions have MAJOR impact for the entire country and they supersede any lower-court decisions and invalidate all conflicting laws.
When the Supreme Court says that separating black and white students in public schools is unconstitutional (Brown vs. Board of Education, 1954), it affects you directly.
When the Supreme Court says women have a constitutional right to abortion (Roe v. Wade, 1973), it affects you directly if you're a woman and/or have had your partner need/want to terminate an unwanted pregnancy.
When the Supreme Court says corporations and unions can spend unlimited amounts of money in elections (Citizens United v. Federal Election Commission, 2010), it affects you directly.
Sure, local politicians may affect more day-to-day life matters, but in the grand scheme of things, those don't matter too much. I mean, if you think the amount of budget allocated to the local school system is too little, move to another city/state with a better-funded school system. Not super easy to do, but moving to another country however is considerably more difficult.
