Name the 'Seven Dwarfs' of the 1988 Presidential Election

In July of 1987 — 70 weeks before the election — seven Democratic candidates appeared together for the first big primary debate. The field had some names you'll certainly know. But at the time, after generally uninspiring performances, they were dubbed the 'Seven Dwarfs.' How many so-called Dwarfs can you recall? (Last names will suffice.)
