What's it about
This cartoon is about how Obama Care isn't working correctly. It shows how he is trying to run something very big, important, and helpful, but has such a bad way of doing this.
20008 - now
The artist uses exaggeration because the ambulance isn't actually being run bya hamster. He's saying you can't power something this big with something this small.
Trying to say
The artist is saying that Obama Care isn't working because he's tring too much at one time with not enough resources to power it. You can't work an ambulance without an engine.
