I agree in general, especially in print. But I'm not sure if a dispassionate appeal to logic and reason plays well in this age of out-of-context soundbite videos. Cruz, Paul, Rubio, and Gingrich sound very good when debating, but someone like McLame, Romney, or Boehner fall flat and it's hard to hear their message with their deadpan, moderate sounding approach.
That is a very important distinction. You shouldn’t moderate your beliefs, or principles. In fact if you do that is blood in the water to libs. But they can’t handle them either, and it will also function to infuriate them.
Moderate the tone, stay unemotional, and the lib will appear out of control.
