But...you know, not my congressman. He's fine. He lives just a few miles away and has been there forever and I like him. I'll leave him. But everyone else! Gone!"
The reason Congress has so many career politicians and remains so deadlocked is that, barring major 1994, 2006, and 2010 esque "revolutions"...most people like their guy...just not anyone else. Multiply that times 400 and you've got a set of trenched people with built in bases and little incentive to change.
With the news covering Congress as a monolith and the Presidency as the only interesting race, it's easy to forget the real truth: all politics is local. If you really want change (and it's ok if you don't) that's where it has to start. And that's usually all you can affect. Take care of the small things, and hopefully everything takes care of itself.
An also, it's important to remember, just like driving in traffic, there's no sense in complaining about a problem that you, yourself are contributing to. You can't bemoan too many cars on the highway...while sitting in a car on the highway. You can't be upset about too much angry partisanship...while yelling on Facebook to elect your person, and you can't condemn the other side of being divisive and dark, and stirring up divisions on your own side. Be part of the problem, or stay out of it...but only one gets to complain.
