"They both switched, in a way," says Barbara Perry, a presidential scholar and Supreme Court expert at the University of Virginia's Miller Center. For Biden, it was "an evolution," she says. A devout Catholic who lost a baby in a car accident, Biden was personally opposed to abortion, a view that was partly reflected in his voting record. But since then, with changing times and views towards women (not to mention being married to Jill Biden, the first first lady to hold a professional job outside the White House), Biden has become a strong supporter of abortion rights, Perry notes. For Trump, Perry says, the evolution was transactional.
