I read this today and laughed;

Democrats think the glass is half full, Republicans think the glass is theirs.

This old philosophical exercise is actually quite helpful in today’s political climate. 

I wish democrats and republicans alike would recognize the whole truth.

The glass is both half full and half empty. Oh.

Optimists and pessimists each have only half the story. The democrats(left) and republicans(right) can’t have the whole truth if they tenaciously hold to their monolithic, limited prespectives.

Nauseatingly obvious, isn’t it?
