As I see it, the most basic nature of conservatives is to resist change. They see what the like about the present and the past and try to preserve it or restore it. They fear change. Basicly they see what is right, right now, and what might be wrong with the future.
Liberals are the oposite. They see what is wrong right now and encourage change, looking forward to what might be right in the future.
Because the now and the past are both very well defined things, conservative tend to agree with each other. Either you agree, or you aren't part of the group. Very elitist.
The future is far more nebulous. No one really knows what it will bring or what will make it better. Liberals have very diverse views on this and rarely. While this does not sound elitist, liberals do have very elitist sub-groups with their own strongly held beliefs.
Liberals are in greater numbers than conservatives, but do to their lack of cohession, they gain power but lose it to infighting.
Conservative on the other hand work well in unity which gains them power, but they lose power in those moments of liberal lucidity, when they manage to rally behind on flag to bring the conservatives down.
This is the nature of the beast and I don't think it will ever change.
But as far as the conservative calling liberals elitists: Pot. Kettle. Black.
