As Democratic gains in the House have continued to rack up in the week following the Nov. 6 election, it becomes increasingly clear that cohabitation in government won’t be easy for President Trump. Democrats reportedly already have nearly 100 subpoenas waiting to go as they begin their oversight of the administration.

To some extent, this is how it has to be – and even how it should be. The Founding Fathers anticipated the adversarial nature of the branches of government, expecting them to check one another. They did not anticipate the partisan system that developed, which sometimes reduces incentives for effective congressional oversight and investigation when Congress and the president come from the same party.
