Joe Biden teased a 2020 presidential run during a TV plug for his new book, "Promise Me, Dad," on Monday.
Biden told NBC's "Today" he's "been around too long" to rule out a 2020 run.
"I'm a great respecter of fate," he said.
Hillary Clinton was unable to get her message out in 2016, Biden said, adding that he does not know if he would have beaten Donald Trump in the general election.
The "Outnumbered" co-hosts remarked that the former vice president's "I've been around too long" might not be the slogan Democrats need.
"You don't see that on the back of a car, a bumper sticker?" Lisa Boothe quipped.
"I think the ship has sailed for Joe Biden in the sense that the party has left him behind," she continued. "There's no way that someone like him, who's a little more middle-of-the-road, would ever be able to get elected in the Democrat primary."
However, Boothe agreed that Biden would have fared better against Trump than Clinton did, especially among the working class.
