Nixon broke into the DNC headquarters to find out about what the opposition was doing. I don't recall him ordering an agency to attack individuals who supported the opposition, or using the law to stiffle them.
If Nixon would have been a Dem the MSM would have declared these guys acting on their own. And the tapes would have never been found. Kind of like e-mails missing today of all IRS employees. Can't just get rid of the senders computer the recepients also have a record of what went on. Equivalent to Nixon erasing the tapes. Nixon took the fall for his actions.
Obama, and Hillory not so much.
