I will repeat a few things that have been mentioned, if you want to have any effect other than looking like a nut, you need to make your signs better looking, and think them through a bit, try to break your message down to two or three words, and make them huge, fill in the rest of the sign with the supporting grammar in smaller words. after all that has been said I still don't have a very clear idea about what you want, your last post was the first time you actually expressed much of anything coherent.
you should try to offer suggestions on something constructive, at the very least you should have a 'do something' position, like "vote 3rd parties, don't care that they will lose."
