Background:
Political corruption is the use of governmental powers by government officials for illegitimate private gain. An illegal act by an officeholder constitutes political corruption only if the act is directly related to their official duties.

Starting in Prisoner of Azkaban, we start to see the Ministry really become corrupt. Beginning with Fudge letting Harry off for 'blowing up his aunt', but nothing really comes of the corruption in that book. The corruption continues as the series goes on, escalating in Order of the Phoenix, with Fudge becoming the "know all" and anyone who disagrees with him, is basically called "insane".

Fudge used his position in power to make Dumbledore look like the "bad guy", who was just out for his job. In reality, Dumbledore never wanted to be Minister. By making Dumbledore look bad, it showed Fudge in a better light.

The Discussion:
With all the political corruption that occurred in the books, was there anyway to prevent it from escalating to its max? How could it be prevented in the future / how could the conflict be transformed into something workable?
