Should I vote today?

[MikeWaters]

I was talking to my dad, who has participated in state convention(s) in the past and is a poll worker this year, that I was thinking I might not vote in the primary.
So he tells me that I should vote and it is my duty.

I had asked him who he thought he would vote for, and he said Romney. "So you want to make a meaningless vote for a guy who has given up his delegates, and you are telling me it is important for me to vote?"

So eventually he decided he would vote for McCain, in order to not be meaningless.

If I vote in the GOP primary, I would vote for McCain.

If I vote in the dem primary, I would probably vote for Obama, because I don't like the Clintons. But the idea of voting in the dem primary to "throw" the election doesn't appeal to me much.

I still haven't decided if I'm going to vote.
