research, my friend, research.

I'll also expose my own sources:

By the way, a presidential write-in candidate (what Nader was in 1992) is a person whose name doesn't appear on the list of candidates but can be written by hand on the voting form. I guess this means in 1992 he was participating as a pure act of protest.

and, least reliable of all, the official biography:

The 1996 elections were easily won by Clinton:

Enjoy the research...
