Let zebras represent the American people.
Let lions represent the old health care system before Obamacare.
Let a tall fence, separating the zebras from the lions, represent Obamacare.

Now..., it used to be that the lions would pick off the weak zebras thus making the zebra herd stronger.  But with the new fence, the weak zebras get to live longer and the zebra herd as a whole is weaker.

In other words, under the old health care system, stupid people could not get a high paying job and thus couldn't afford health care and subsequently died off leaving the smarter Americans behind and insuring a stronger America.

Obamacare forces smart Americans to work that much harder in order to take care of the weak and thus making it more dificult for America to stay competitive in the world.

It is a well known fact that stupid people breed faster than smart people and it may be the case that the number of stupid people have finally surpased the number of smart people in America.  If this is the case, then Obama will win a re-election.  But if that's not the case, Mit will win and he'll overturn Obamacare.
