Yeap
But I've learned the pendulum usually swings back. If Democrats go wide left and get crushed the next candidate will be more moderate. If they win with a lefty the next Rebuplican will be more moderate and probably win. Go to extremes and you usually loose the midterm elections. I'm not surprised however that people that ignore 10 year patterns of behavior in Iraq or ignore lab data to claim obvious environmental risks are scare tactics can't see the pattern.
