As we approach the 50th anniversary of the assassination of President Kennedy, the University of Virginia is offering an on-line course called “The Kennedy Half Century.” It’s spearheaded by UVA political science professor Larry Sabato and looks at Kennedy’s life, assassination and legacy. Sabato says a lot of time and money in the course, which is available on-line beginning today. He says the course is free and people have signed up from all over the world to take it. You can sign up here, or through I-tunes University.
