Instead of Congress, we should take everyone who when they were 4 wanted to be president when they grew up, and then put all of them into a Hunger games-like arena where all of them fight until about 200 are left. Then those 200 become our leaders to sort out the government stuff, and if their approval rating drops to below 30% we have another hunger games fight.
Best part: We can watch politicians literally kill each other just to get our approval
Congress should not be replaced. The way Congress is set up works very well, and any shortcomings of Congress come from the people who are in it, not the institution. Congress can be made better if we impose term limits on how long members of Congress are able to serve.
