That seems to be a very oversimple approach. Cities are the most obvious problem. You kind of want a population center to have a single congressmen representing it. Mathematically, you want districts to be fairly compact. There have a been several Operations Research papers that try to do things in a more practical way. Also, a greedy approach (split in half, repeat) seems weird to me.
