No, I'll give you my logic. I live in a deeply blue state, IL. There was 0 chance of Obama losing IL. So I supported a 3rd party candidate because these 3rd party candidates need to get so many votes in order to be eligible to get back on the ballot in future elections. I will always support their cause when I can because one day myself, or perhaps you, will want that "choice". And people like me will allow for that to happen. So by not voting for two candidates who I did not agree with and actually voting for the candidate I did believe in, I not only only made the right choice per my beliefs, but I helped further my cause in the future when this country is going to desperately need that 3rd choice on the ballot.
Okay, against that background I can see your logic. We just disagree on the merits of one of the two principal contenders at that time.
