That’s an ominous sign for Joe; recall the articles from mid-2008, when another older man with a long history in DC ran for the White House, such as this one in the New York Times headlined, “McCain a One-Term President?”
Curiously, back in April of this year, USA Today had the headline, “Joe Biden, 76, says he has no plans to limit himself to one-term in the White House.” But then, over the decades, Joe has always said plenty of malarkey.
