The issues of politics and administration dichotomy first raised by Woodrow Wilson continue to generate debate among scholars of public administration in the modern time. People think that his idea was useful, but others think it was impossible. Is that distinction practical and workable, and are there advantages to using such a dichotomy today as a way to advance that field of study?

It is understandable why, during Woodrow Wilson's time, the distinction between politics and administration was clear and distinct. The federal administrative state was nowhere near as big as it is today, and civil service reforms had just been enacted following the assassination of President Garfield by a disgruntled civil service job applicant. The belief was that the administration of government should be separate from the politics required to gain elected office.
However, as the administrative state has grown, and presidents, governors, mayors, and other elected officials have gained more power as a result, the line between politics and administration has blurred. At the federal level, Congress's abrogation of its legislative power and the growing prominence of executive orders and administrative rulemaking have led presidents, under political pressures, to appoint more partisan candidates to administrative bodies.
The recent debate over Net Neutrality is an example of politics invading and erasing the dichotomy with public administration. Until 2015, the Federal Communications Commission determined that it had no authority to regulate the internet, but under political pressure from the Obama Administration, it issued unprecedented rules changing the classification of the internet. Two years later, thanks to a change in the White House, and under the influence of different political pressures, the FCC rescinded the 2015 rules and returned regulation of the internet to the status quo ante.
As we see administrators subject to more political pressure because of their increased authority, we can expect to see more and more rule-making subject to the changing winds of politics until the legislative bodies provide clearer direction, removing the ability for administrators to play politics with the rules.
