The first 100 days of a presidency traditionally has been regarded as an important time period. New presidents typically pass through Congress at least one important part of their agenda during this time frame. Congress usually extends a certain amount of good will and deference to a new president by enacting one or more key agenda items.
For instance, during the Obama presidency, Republicans helped Democrats pass his fiscal stimulus and the Hi-Tech Act very quickly. These were very statist pieces of legislation. Congress gave Obama what he wanted, regardless of the merits, within a few weeks of his inauguration.
President Trump has had some big successes. He has been able to influence policy via administrative action-- executive orders, agency actions, etc. He has gotten Neil Gorsuch confirmed.
Of course, it will be interesting to see to what extent Gorsuch will turn out to be an asset in the culture wars initiated by the left. During his confirmation hearings, he stated emphatically that the Obergefell ruling that forced same-sex marriage on the entire country is "settled law". He is part of the Episcopalian denomination that allows gay bishops and that blesses same-sex marriage. If he is ultimately able to help overturn Roe vs. Wade, it would be an enormous achievement. But perhaps we ought to be trimming our expectations a bit regarding Gorsuch.
Republicans in Congress have repealed some of Obama's regulations on their own initiative. But that has really been the extent of any semblance of a conservative agenda being implemented on Capitol Hill.
It has been quite obvious that Paul Ryan and Mitch McConnell do not want to implement Trump's agenda regarding immigration and trade. There has been virtually no movement on these issues within Congress.
Trump and Ryan teamed up to try to "repeal" Obamacare by amending it. It was a fraudulent effort; and turned out to be a monumental failure. Simply put, the Republicans are not going to take away a major entitlement program despite the fact that they promised to do so many times over a prolonged time frame. There are certain special interests that benefit from Obamacare; and they make campaign contributions to Republicans.
The attempt to tar Trump with allegations regarding entanglements with Russia was openly advocated by both Republicans and Democrats in Washington. These establishment players were clearly trying to prevent Trump from developing closer relations with Russia; and they were also trying to impede other aspects of his overall agenda. There were even unstated (and stated) threats of impeachment.
They successfully got Trump to alter his stance regarding Russia. Moreover, they likely created an environment that led to his bombing the Syrian air base. He adopted the quick-trigger military interventionism favored by some of his most severe critics. Let's hope this does not get us into trouble if he persists.
The pace of replacing Obama functionaries in the various federal agencies has been very slow, in part because of Chuck Schumer's deliberate delaying strategy in the Senate. Trump has available to him many potential federal judgeships also for which he can make nominations; and he has hardly even begun this task. Even if he did, Schumer would try to hold them up.
The nominations within his administration have been packed with establishment players, Zionists and foreign policy interventionists. From this standpoint, it is beginning to look like a GOP establishment presidency.
There have been numerous decisions by corporations to make investments and hire large numbers of people within the United States, apparently in anticipation of Trump's proposed tax and regulatory changes. But the Republicans have not arrived at a consensus even on tax legislation. Complications abound.
The Trump presidency is decidedly better than whatever a Hillary Clinton presidency would have been. However, the output of the first 100 days suggests that much of the benefit from his presidency will arise because of administrative action he and his appointees can take unilaterally. (The 100 day period will elapse at the conclusion of this month, and Congress is taking a two-week recess.)
It will be interesting, nonetheless, to observe how Gorsuch performs on the Supreme Court.
