La Follette's refusal to compromise his principles earned him the name "Fighting Bob." He insisted: "In legislation no bread is often better than half a loaf." La Follette–a skilled parliamentarian–used the filibuster to stand up to special interests and to push social reforms, such as workers' rights and child labor laws.
