Marc Allan Feldman has died. He was one of the most energetic campaigners for the Libertarian Party’s presidential nomination last month in Orlando, receiving 58 votes on the first ballot, placing fifth. He was an emergency room physician at Cleveland Clinic. See this description of him from the Clinic’s web page. He had an excellent sense of humor and won the admiration of the convention attendees with his satiric rap performance. UPDATE: see this news story. Thanks to Jackie Donahue for the link.
