Several Democratic presidential candidates are advocating to expand public service programs in America.
Why it matters: Proponents, such as former Rep. John Delaney (D-Md.) and South Bend Mayor Pete Buttigieg (D-Ind.), say public service builds morale and is a means of developing shared values. Their programs also claim to provide opportunities for those at the start of their careers to build skills, resumes and networks. But their approaches have an important difference.
