The Republican Party has the unenviable record of having six of their Presidents leading the nation in major periods of corruption, sometimes with their support, and other times because of poor selection of advisers and cabinet officers.
Chronologically, they are as follows:
Ulysses S. Grant–1869-1877
Warren G. Harding–1921-1923
George W. Bush–2001-2009
The two worst are Donald Trump and Richard Nixon, while the others seem not to have engaged personally in scandals!
But all six Republican Presidents had people in their administrations face indictments and convictions!
While there was minor scandals under some Democrats–Harry Truman, Lyndon B. Johnson, Bill Clinton—they, in no way, match the horrendous record of the Republican Party!
And two recent Democratic Presidents have a totally clear record of no corruption, no indictments, no convictions—Jimmy Carter–1977-1981, and Barack Obama–2009-2017!
