They had to take a poll to find this out?
We conservatives do not have to get up on the morning defending lies. We don't have to spend our time erecting wall after wall to keep out the truth (see "DU"). We don't live our lives in politics. We don't go through everyday knowing that our "enemies" know we are phony nutcases, and that we know we are phony nutcases pretending not to be phony nutcases.
No liberal can be truly happy. It is impossible.
Taking this poll makes about as much sense as taking a poll of normal everyday people and prison inmates and discovering the normal everyday folks are more satisfied with their lives.
