In addition to serving in the State House, McCravy is an attorney and teaches law at Lander University. He is the primary sponsor and architect of South Carolina's fetal heartbeat bills.
In May 2025, more than two dozen members of the South Carolina house resigned from the Family Cause due to McCravy's relationship with out-of-state anti-abortion groups that openly criticized members of the Family Caucus.
