Personally I would still vote, for the simple reason that choosing not to vote is still a choice
, so why not make the choice count?
If you don't like either candidate, that's fine too, however, there is such a thing as the lesser of two evils. Choosing not to vote either way means you're potentially increasing the chance that the greater of the two evils gets elected.
Note as Louise mentioned, in N.Y. it might not realistically make a difference, but does anyone want the chance of the greater of the evils getting in? Siding with caution says, why not vote?
And a further note to those who would select an outside candidate, that is your choice and your right, but with the majority selecting one of the two the chance of a third getting elected are remote, so again why not select the lesser of the two evils to ensure the greater doesn't get elected.
Just my .02 cents on the matter.
