I think it's because Reagan was the first president we were old enough to really "see" and understand as the president. We watched him on TV when we were kids, we remember him being shot and he made an impact on us. (I'm not sure, but I would think Boomers may look at Kennedy the same way.)
Hardly. I was 4 when JFK was shot.
Nope, I was 5 when Kennedy was shot. My mom was 23. She was devastated.
