But when it came to saying whether his wife, Hillary Clinton, or his daughter would be a better fit for the job, Bill Clinton couldn't quite choose.
"Day after tomorrow? My wife, because she's had more experience," Bill Clinton told CNN Wednesday. "Over the long run? Chelsea. She knows more than we do about everything."
"There was a time in her childhood when she thought she did, when she didn't. Now, it's highly embarrassing, because she in fact does," Bill Clinton added with a laugh. "I feel like I'm going to school every day when we have conversations."
Hillary Clinton, the former first lady, senator from New York and secretary of state, is currently weighing whether to run for president again in 2016 -- but Chelsea Clinton has only recently announced her intent to ease into a career arc more in the public sphere.
This year, Chelsea Clinton took on the role of vice chair at her family's Clinton Foundation.
