He could have been a janitor, but for the Liberals. He is a disbarred ex-lawyer, who was a part time guest lecturer at some college in Chicago. Other than that he has no qualifications or experience to do anything at all.
There was a reason he campaigned on "Hope". That is all he had to bring to the table. His resume' is empty and buried at the center of the Earth, so no one can ever see it. His college transcripts are locked in a six foot thick vault somewhere with armed guards around it. The guy is a ghost, with no past and no experience.
So yes, but for his lucky election in Chicago, and the seemingly boundless stupidity of Liberals, there is no way to tell what 'job' he would have today. It is possible the guy could very well be working as a janitor. Instead, he is President of the United States. Try to figure that one out.
