Obviously, we NH residents get to see a lot of these campaigners up close. Bush, Perry, Chaffee, Graham all marched in my towns parade on the 4th. I have personally shaken hands with many over the years.
Like you stated, most of them actually like it, you can tell by their attitude, they are extrovert personality types. I remember when Kerry came through, he seemed to like “pressing the flesh”, smiling his big horse face smile for the camera. He is ten times more personable than Hillary seems to be. Yet, he came off as being aloof on TV. Hillary’s biggest problem is she is just not likeable. She has no charisma. She is not charming. That is why her handlers limit her exposure. That is why she was vulnerable to a first time Senator with zero experience. That is why she is vulnerable now.
