Democratic presidential candidate Joe Biden claimed that he’s “not going nuts,” despite yet another gaffe at a campaign stop in New Hampshire.

Biden, 76, was at his second campaign stop of the day, after speaking at Dartmouth College.

“I want to be clear, I’m not going nuts,” Biden told the crowd after forgetting where he had just given a speech a few hours earlier. “I’m not sure whether it was the medical school or where the hell I spoke. But it was on the campus,” Biden added, according to a report from the Washington Examiner.

During a previous trip to the state Biden also mistook New Hampshire for Vermont, saying that “I love this place. Look, what’s not to like about Vermont in terms of the beauty of it? And what a neat town … everybody has been really friendly. I like Keene a lot.”

The blunders have lead to many questioning if the septuagenarian would be able to take on President Trump in the election, let alone run the White House.

“It’s a cause for concern if you’re running for president, especially if you’re not sure what state you’re in,” Phil Johnston, the Massachusetts Democratic Party’s former chairman, told the Boston Herald. “We all love and respect him, but in 2020 we have to make sure the nominee is up the task of taking on President Trump.”

“He needs to show he’s up to the task of being president, day-in and day-out for the next 14 months,” Johnston added. “If he continues to make these mistakes, many people will be concerned.”
