Because the amendment’s main backer is Crist’s boss, it has raised suspicions among some voters about its true purpose. Personal injury attorney John Morgan is chairman of the pro-Amendment 2 campaign and Crist’s employer.


Crist says he supports the measure “out of compassion” for suffering people including his older sister, who was diagnosed with brain cancer.


Scott says he opposes Amendment 2 because he has had relatives who have battled substance abuse.
