That was Tom Campbell. I believe he's now a tenured professor at Stanford University. When Stanford offered him tenure if he taught full time (instead of part-time, with most of his time being spent in Congress), Campbell decided to challenge Dianne Feinstein in the 2000 Senate race, since I guess he figured that if he was going to forgo tenure at Stanford it might as well be for a 6-year job. Running to the left of Feinstein on social issues is no way for a Republican to mobilize the base, and he was defeated handily.
DJ, if I got any details wrong, please correct them (I was paraphrasing what I read in Mike Honda's page on the 2002 Almanac of American Politics).
All true. Although a lot of Campbell's record was subpar - there was one thing that stood out. He had the courage to vote for Impeachment in a pro-Clintonista district. He could've taken the weasel way out or kept to a RINOista path, but he didn't. He at least had my respect as far as that was concerned.
