I've been thinking about this a lot and I really think that it comes down to reducing the number of representatives we have. Partisan politics have largely formed due to the power of groups in Congress...as Congress has gotten larger and larger the power of each individual has weakened while strength in groups has grown to the point where the individual has little to no say (esp in the House). Our first Congress was roughly 15% of the size our current Congress is. This allowed for each individual member to have a much stronger and more powerful voice. If you want to get rid of group think in Congress you have to increase the power of the individuals. However, that comes with obvious downsides if the wrong individuals are elected. It is a trade-off.
What you propose is about the dumbest ******* thing you could do. You want to concentrate all this power into the hands of LESS people?? You want to increase the size of their fiefdoms? The average member of the House represents approximately 700,000 people. How can one person effectively represent that many people? They can't. That's why Washington is so detached from the rest of the country. Have you ever tried getting a meeting with your Congressman? Good luck. It's hard to make time for 700,000 people, but it's easy to meet with lobbyists who are right over on K Street.
What we need is to double, if not triple the size of the House, one member of Congress representing 250,000 is going to be far more responsive to their constituents than one who is representing 700,000 and the power is spread out over many more people as opposed to being concentrated in the hands of an aristocratic few. It's also a lot harder for lobbyists to bribe 1300 members of the House than 435 and in fact, they don't even need to buy 435, just 50% of them plus one. Given the size of this country our Congress should look like the Republican Senate in Star Wars.
They should also spend more time at home and less time in Washington. With all the technology we have today why do they need to have a physical quorum in D.C. in order to hold a vote. Why can't we have a couple thousand representatives voting from their home districts? Wouldn't that make more sense?
New Hampshire is one of the smallest states in the country, yet it has over 400 members of its state legislature who get paid $200 a year and the state is run pretty damn well.
