Bob Marshall doesn't believe that Gays and Lesbians should be allowed to walk [er, parade their perversions] among us. He doesn't believe in women's reproductive rights, and even got involved in the Terri Schaivo case.
Bruce watched Bob Marshall for a long time and wondered "Why doesn't somebody do something about this guy?" After a few years of watching, and working on campaigns, he decided to do something about Bob Marshall.
Bruce believes in the inherent worth and dignity of every person [except Conservatives, people who don't want to pay tribute to union bosses, unborn children, and Terri Schiavo], which puts him directly at odds with Bob Marshall. This is an opportunity to live your values, and that's just what we need to do.
The saddest thing is that their own contradictions are probably lost on the boys and girls over at Raising Dough ... er, "Raising Kaine."
