No but most of us are realists and realize that our society has a two party system and a show with 50 voices would make no sense.
But within the parties there are variations and streams of thought.
Is the public only served when ONE ideology from Party Red is put into the battle against ONE ideology from Party Blue?
Are the parties not better serve, and in turn the Republic better served when we also get to peek behind the curtain and understand what is going on within the parties?
Maybe we could say "A show with 50 voices would make no sense...... to those with limited mental abilities and limited curiosity.
