Yep, you should all definitely vote if you possibly can. Even if you are on different opinions about various candidates, the worst thing anyone can do is not vote.
On a sort of offtopic, when my country voted for it's European Parliament representatives, only 35.7% of the whole country (460k out of 1.3M) voted and it was HELL after it, people complaining about the winning candidates. Luckily, my party won big-time, but if, say, 50% or 60% voted, the final result could've been completely different.
You may think that one vote doesn't count, but it does and unfortunately so many people think that way (I can't imagine how many millions skip voting in USA).
I usually don't make so long comments lol, buuuut while I'm at it, here's another EVEN BETTER example, again from my country. In 2009, when we previously voted for our European Parliament representatives, one party almost got 3 positions out of the total 6 that we have. They LITERALLY had 6 votes too few for 3 positions and got 2 instead. SIX VOTES!
So next time you think your vote doesn't matter, think of these stories. I'm not sure what's the average percentage of voters from USA, but I'm guessing there are quite a lot who don't vote (as in numbers, not percentages [especially compared to my country]).
