Glad to see you're re-thinking that, but if you remember what you learned in third grade you would realize that in a two party system any failure to vote for the least undesirable candidate is mathematically equivalent to a vote for the most undesirable candidate.
My not voting for Romney would be a reflection on the poor quality candidate that he is. It's not a reflection of any desire to see Obama re-elected.
I know that you think that you sound smart, but if you want to see conservatives vote for Romney, you should shut up while you're ahead.
