A vote for Gary Johnson is not a vote for Mr. Obama or Romney. It is a vote for Gary Johnson.
I cannot blame anybody for not voting for republicans or democrats. I almost never vote for republicans and never vote for any democrat. A lot of republicans harshly criticize those who vote for the candidate of their own choice instead of for whom the republicans prefer. If the republicans want conservatives to vote for them, run a conservative.
I'm going to vote for Romney, only to vote against Mr. Obama.
