That's laughable. J. Edgar Hoover was a wonderful tool for...multiple democrat Presidents. That few democrats are ever charged for abuses of power merely proves my point.

Hoover is widely seen today as an autocrat who used secret surveillance and other illegal means to control politicians and infiltrate and disrupt domestic political groups in the service of his conservative worldview. No operation confirms this verdict more vividly than the FBI's wide-ranging electronic surveillance of Martin Luther King Jr., which culminated in a threatening letter to King accompanied by tape recordings of romantic trysts'an effort designed to drive King from the civil-rights movement or induce him to commit suicide.

Well, you can compare convictions from 1968 on of Administrations and see what you get. Prior to 1968 it has to be looked at as to whether it's conservative or liberal.
