Stone, a freshman senator, had a reputation for changing his mind. In 1980, the AFL-CIO actively campaigned against him, and Stone was deemed vulnerable in his re-election bid.[2] Six Democrats entered the race for Stone's seat including his 1974 runoff opponent Bill Gunter who was Florida State Treasurer/Insurance Commissioner in 1980.[2] As was the case in 1974, Stone and Gunter were forced into a runoff but, unlike 1974, Gunter won the nomination.[citation needed]
