I would be astonished if he wasn't hired at a prestigious university, even after being thrown out of his current gig. Big universities love celebrity professors, especially ultra leftists. UCSB hired Angela Davis for instance.
Thing is, getting fired because of plagiarism is the kiss of death in the academic world. You can do almost anything else you want, including come up with wild theories not based on evidence, but if you steal some other academic's work, you're done for. Nobody will touch you after that.
He might go on the speaking circuit, but he won't be a prof.
IIRC, Churchill's wife was just hired by a university in Georgia, so my guess is he'll be showing up in that area if he does get fired.
