For those naive enough to think that voting doesn't matter, be mindful of your own life and aspirations and pick someone knowing that there is always a worse choice. You do this because you don't have any right complaining years down the line when shit hits the fan because there will be a president whether you like it or not.
Except there are only a handful of states where your vote actually does matter due to the system in place. "Every vote matters" is simply not true due to the electoral college. If you're in a state where the race will be close, sure your vote matters. If you're the majority of Americans in resoundingly red/blue states then your vote is essentially garbage if you're voting for the candidate who is not going to hold your state.
