Hmmm ... I have been known to do that from time to time (since I am known to have a stubborn, curmudgeonly bone or two in my body), but it has a nasty habit of not making any difference whatsoever in the actual election results. As for alternatives to Barry Soetoro and Mitt Romney (for whom I did not cast my Texas primary vote for, by the way), if you are possibly suggesting Ron Paul ... well ... even though I truly like a great deal of what he stands for, I also find him extremely unpalatable in other areas. As a potential candidate for POTUS, I actually like his son, Rand, much better than I like him.
