Pete Buttigieg, the youngest 2020 Democratic presidential candidate in the race, is pushing for a new crop of talent to lead the party.

The age of top Democrats has been a talking point as younger members seek generational change to move the party forward.

Buttigieg, the 37-year-old outgoing mayor of South Bend, Ind., said at a campaign event in Iowa on Friday that the concerns facing America — such as climate change and cybersecurity — “deserve leadership from a new generation.”

“I guess I’m offering myself up as a member of that generation of leaders,” he said.

Yet, regardless of age, Buttigieg vowed to support whoever is nominated to challenge President Trump.

“I plan to support the Democratic nominee in 2020. Period,” he said.

The debate over age is likely to become more heated in the next year as the nomination process carries on. Some of the top-tier candidates or expected contenders are already well past retirement age.

Sen. Elizabeth Warren, D-Mass., will be 71 in 2020. Former Vice President Joe Biden and Sen. Bernie Sanders, I-Vt., will be close to 80 years old.
