Regardless of who you support, please make sure you go out and vote tomorrow. It's important. Even if you are a Republican who lives in DC or a Democrat from Kansas. It doesn't matter if you vote for Hillary Clinton, Donald Trump, or Vermin Supreme. It's important that you take the time to vote. It's important you take the time to understand what you believe in and who most aligns with your beliefs.
If you don't like the two mainstream candidates, seriously consider skipping the presidential ballot altogether or voting third party. But far more important are the dozens of other elections in YOUR precinct tomorrow. Elections that choose your judges, governors, and even local referendums, propositions, and constitutional amendments.
If you don't like the mainstream parties, perhaps the most important thing you can do is vote on these propositions and referendums. They include votes about how you want your state legislators to be paid, school funding, marijuana legalization, infrastructure funding, gun control, minimum wage, and even whether porn actors should be required to wear a condom. (Ok fine, not all of them are important.)
If you don't want to learn about these races, fine, I think that's shirking your duties as a citizen and ignoring the small miracle that voting represents. Certainly it's your right. But if you can't take more than 30 minutes to learn where you're going to vote and do so, then that's extremely disappointing. As Louis C.K. put it, don't be an "a__hole", go out and vote tomorrow.
Apathy cannot be fixed with inaction.
