But they keep doing the same thing expecting different results...which sounds IS crazy.
Observed this when we lived in CT and watch Romney debate Ted Kennedy. His entire campaign was that he could "out-liberal" Ted Kennedy. Ergo, I knew Obama was going to be re-selected when Romney got the nomination.
e.g. ""I am not unaware of my opponent’s considerable record in the area of civil rights, or the commitment of Massachusetts voters to the principle of equality for all Americans. For some voters it might be enough for me to simply match my opponent’s record in this area. But I believe we can and must do better. If we are to achieve the goals we share, we must make equality for gays and lesbians a mainstream concern. My opponent cannot do this. I can and will.""
