I understand your sense of disgust about Romney, but do either of you care about the future of your children and/or grand children?
Every reason you give for not voting for Romney to get rid of obama, is magnified thousands of times if obama wins and those future generations will pay the price.
Go have breakfast with your wife and do some gardening, and pretend that there is a moral equivalence between Romney/obama and then your conscience won't keep you awake at night, and you will have "remained true to your principles".
I can only vote for what I do believe in. I have control over one thing. My vote. I will cast it in support of conservative and yes, christian ideals.
The rest of America can either join me in doing so or not bitch when they are stuck defending themselves for the next 4 years every time their chosen leader sticks it to them.
That simple.
