30. Here's the actual news clipping:

President Kennedy was elected while I was at the University of Chicago, that was 1960. I remember being physically nauseated at his speech and that doesn't happen very often. He debated Nixon on Cuba. And their hated for the Cuban Revolution, both of them, was so strong. Kennedy was young and appealing and ostensibly liberal, but I think at that point, seeing Kennedy, and what liberalism was, was probably a significant step for me to understand that the conventional politics or liberalism was not was relevant.

Why would Kennedy's opposition-to and "hatred for the Cuban Revolution" elicit such a response from Bernie? That sure sounds like the reaction that someone would have if they have a certain "fondness" or respect or admiration for the Cuban Revolution.

It's pretty clear what he's saying and what he's getting at there. He even repeats it for emphasis at the end.
