7. Smaller districts lean GOP and return results early

This is the mechanics of the situation: the smaller the district, the less likely it is to be urban, and thus the less Democratic it is going to be. There are fewer votes to count in these districts, so early returns always skew towards the small-district demographic, i.e. rural, GOP voters.

As the night goes on, districts with a higher population (more urban, and thus more Democratic) are still counting votes while the smaller districts are done. So it looks like the GOP has a lead when they really don't. They could be getting wiped out in a wave election and this phenomenon would still be happening.
