"I say if they're concerned, don't vote for me," Biden, 76, said to reporters.

Biden has faced criticism for his age and stamina since the launch of his campaign in April. Recent polling released by CNN shows that Biden still leads the pack of Democratic candidates by double digits, but some have raised concerns about Biden's consistent speech gaffes.

At the same campaign stop in New Hampshire, Biden misstated the year of the assassinations of his political heroes Robert F. Kennedy and Martin Luther King, Jr. as being in the late seventies, not 1968.

"Just like in my generation, when I got out of school, when Bobby Kennedy and Dr. King had been assassinated in the '70s, the late '70s when I got engaged," Biden said on Thursday.

On Friday, the former vice president again mentioned RFK and MLK, who died within months of each other by an assassin's bullet in 1968.

"I have one hero who was my dad, but I have two political heroes were Martin Luther King and Bobby Kennedy. My senior semester, they were both shot and killed," he said.

Biden then compared President Barack Obama to his assassinated heroes, telling attendees to "imagine what would have happened if, God forbid, Barack Obama had been assassinated after becoming the de facto nominee. What would have happened in America?"

Biden has also been critiqued for misstating personal details of his own life, including that he was vice president during the 2018 mass shooting at Marjory S,toneman Douglas High School in Parkland, Florida.

"Well, I like Biden, he just keeps saying dumb stuff," said an Iowa resident during a recent campaign stop in Des Moines, Iowa. "He feels comfortable in interviews, but his staff just needs to really consider what they're letting him say."
