After the shit he pulled, he would never have a chance running against anyone.
When you are the person that is in charge of enforcing the law, and Congress wants you to answer questions, and you tell them to go fuck themselves, your career in politics is over.
The stupid Democrats ran the worst Secretary of State this country ever had for President in 2016 so why not run the worst Attorney General to ever hold the office in 2020?
Holder is still facing contempt of congress charges after he refused to testify about the monumental debacle of "Operation Fast and furious". It's possible that he could face negligent homicide charges for the death of the Border Patrol Officer who was killed with one of the weapons that he authorized to be shipped to Mexican drug cartels. He sounds like your typical cowardly incompetent democrat candidate.
