It could be said that covering politics is a lot like covering sports: campaigns as horse races, blind and often destructive team allegiances, and so on. But it goes in the other direction too: Covering sports is often an extremely political exercise. That's particularly true in the way that, no matter what, any new piece of evidence reinforces our previous beliefs.
Case in point: No matter how a given season plays out -- with a couple of obvious, dominant teams at the top or with far more parity and chaos -- it reinforces our established beliefs in how college football's national title should be determined.
