A Common Sense Party implies that participants would be drawn from folks who practice rational and reasonable dialogue as a means to developing common sense policies.

I feel like this forum is more prone to rational and factual dialogue than many, though it is currently liberal-leaning (in the present meaning of liberal).

Does anyone know of a conservative-leaning forum that is similar?

To change something, build a new model that makes the old model obsolete.
