In this diary I plan on compiling a list of competitive House races that, eventually, I will change into a ranking system similar to the one SSP uses. I am going to include any races I think have even the slightest potential to be competitive, and will narrow the list down later. Some races have competitive primaries, I have chosen the person I perceive to be the front runner. If I leave any races out, please let me know in the comments. Thanks!
