Third party candidates are not likely to be much of a factor in this year's Presidential race. Candidates for the Green and Libertarian parties will attract votes from those wanting to make a statement on issues like personal freedom, drugs, wars and so on.
Those voting in New York can make such a statement without worry since NY is so lopsided for President Obama. Those living in a swing state may want to balance the need to make a statement with influencing the end result.
In any event, those choosing to vote for a third party candidate should not be cowed by convention and statements about "wasting" a vote.
No vote cast is wasted. It's your property. Do with it as you wish.
