At least 4 years ago I read an article someone had published about how
he had taken a year off college to follow either the 1992 or 1996 (I
don't remember which one) presidential campaign as a journalist,
recording youth-oriented campaign reports to a voice mail box, which
was subscribed to by several college radio stations.

Part of his story involved slipping out of the press box during a
question and answer session with the public and asking a candidate how
one could support a person's right to scramble his or her brains by
not wearing a motorcycle helmet but not support a persons right to
scramble his brains with marijuana.

Who was this young journalist, is this article still online somewhere?

Here's a possibility:

"Josh Fine, who started a one-man network of college radio stations to
cover the 1992 presidential campaign"

Brilliant! I went to the library and found that book and it jogged my
memory. It was that book not a web page that I was reading, and I'm
mixing a couple different sources up in my memory, the
drugs/motorcycle helmet story was probably written by Al Franken.
