One Party Government

While most of the time the President, Senate and House are not all of the same party, Trump, Obama, Bush 43, Clinton, Carter, Johnson, JFK, Truman and FDR all had at least one congress that was entirely aligned with them. Those with more than one congressional term aligned with them were Carter, Johnson, Truman and FDR. With the exception of Carter, legislative agendas and government initiatives under the other 3 were broad sweeping and shaped the future of America. Everything from the WPA and Social Security to the Civil Rights Act owe their origins to one party government.

As Trump assembles his team, he will not only have to put together the executive branch and appoint the vacancies in the judicial branch, he will negotiate with the new Congress who the leadership will be in the house and senate. Paul Ryan is clearly dead in the water as Speaker of the House. This new congressional leadership will be the key to Trump's effectiveness as a president and to the range of impact that his policies will have. If history is a judge, he will need not only this congress, but the next one as well, to achieve his most dramatic goals and objectives.
