Whether you are talking about individual signage or just stupid things people say, politics is about the art of persuading people. This signage is basically what the people who are becoming the face of the conservative movement are doing. I don't know when it started, but I am seeing it everywhere- in person, on billboards and on the internet. They are free to do it, but it won't get them anywhere and I consider it a shame.
One person even told me they won't sacrifice their morals for the sake of electibility. My response was that she can't take her ball and go home, because the left already took the ball away.
