Sure you have a choice, the same one I will be making - write in Chuck Norris or leave the POTUS/VPOTUS slot blank on your ballot.
There is no way in Hell, Heaven, or Earth that I will vote for either of the nominees. Except for complexion, I see no difference between them and the ideas that these people hold dear are anathema to me. I have no representation any more above the congressional level.
I will not write someone else in. I will vote for Romney, as difficult as that will be. The more people who don’t will give all the more strength to the Democrat vote. Sorry, but I’ll not enter into a 2nd Obama term (hopefully not...) knowing I did nothing to prevent it.
Please consider not leaving it blank. It is better to put any name in the field than to leave it blank where the potential exists for anyone to put in their choice for you!
