I thought about that today. We have only two choices. We cannot vote for someone we want, so we are left with voting for the best of two choices. This appears to be the reality of the situation. Before God this is a very hard election. I am praying that I make the right choice. Right now I am thinking that I will have to vote for Romney, but for my souls sake, I still am asking God if this is the right thing to do, or do I write in a candidate?
That is a very legitimate way of looking at it, as is for those who just cant pull the lever for Romney because he is a lib. In fact in many states it doesn't matter anyway, like my state Maryland.
Having been in the same position in 2008 I have given this some thought.
Here is the irony of the situation. If you actually vote (for MR) then your conscience might rest easier if he loses, alternatively if you don't vote out of principle (or you just don't like him) then it will be easier if he wins.
The reason why is belong the gloating stage which ends mid January (or could be sooner) when the real Romney takes office and everyday is a surprise. Alternatively if Obama is re-elected no good will come out of it.
Southpark did an episode on this situation years back where the Town people kicked Stan out of town because he refused to vote for either piece of crap in a school election.
