Caleb Lack (fellow SINner at Great Plains Skeptic), on facebook, succinctly stated:
So, I watched the whole Dem debate, just like I watched the whole Repub one. My takeaway:
Dem candidates want positive change and have ideas how to accomplish it. Most are playing to a sense of community and pride in what we can be.
Repub candidates want to show you how much they hate various things and people, and want to play to your negative emotions (fear and hate, in particular).
To me, this sums up the difference so obviously exemplified by the candidates, not only in debate, but in pretty much everything they say. Nuff said.
