a political system in which changes in congressional control are rarer, and are talked about more rarely, is going to be a political system that both is and feels far more stable in its hierarchies. This is key to Lee’s point. When one party is perpetually dominant, the subordinate party has reason to cooperate, as that’s its only realistic shot at wielding influence. Either you work well with the majority party or you have no say over policy, nothing to bring home to your constituents.
