They can say, 'If I’m elected I will do X, Y and Z,’ but only an incumbent congressman can actually submit a bill,” said Larry Sabato, director of UVA’s Center for Politics. “As deceptive as that is, only a tiny slice of submitted legislation ever becomes law. Frankly, most people don’t know that.”
