Despite all the rhetoric of Republicans "controlling" the government after the election, it pays to remember that the Senate is still very close, the Supreme Court is divided, and an awful lot of the 96% of people living in DC who are Democrats work in government. You can call it narcissistic entitlement, or just clever politics, or a better grip on reality, but when Democrats have 55 Senate votes they consider it a narrow majority and don't begin to get comfortable until they get to 60 and can do as they wish so long as they have no defectors. Republicans have not seen anything resembling the majority spikes the Democrats occasionally get. It's not "control." It's not anything like control. It is still give-and-take and scrambling for the last few votes and debating about whether a filibuster is fair or not.
Not to mention that Trump is inexperienced. In the campaign he seemed to adapt quickly and break new ground, but I don't know if that will continue when trying to govern.
