Who voted / supported Bradley in 2000, and why?

Just curious ... must have had my attention elsewhere at the time, because I never caught up with the what and why of the Bradley candidacy. I tuned in in time to get McCain, but not Bradley.

Of course I could Google up info about it, but way I figure is, if what I want to know is what made people choose / support him, who else to ask but them? So - help me out here? Thanks
