While the Biden campaign released an ad last month which praised the president as being "sharp as a knife," his critics reject that diagnosis.

They've long accused Biden of suffering from cognitive decline, and an incident this week seems sure to bolster those allegations. 

"After I signed the pacandlpacatlackack into law"

According to Breitbart, the president touted the Honoring Our Promise to Address Comprehensive Toxics (PACT) Act while speaking at an event in New Hampshire on Tuesday.

Biden signed the legislation into law two years ago, and it expanded benefits for veterans who have been exposed to Agent Orange and other toxic substances.

However, Breitbart noted that as the president was nearing the end of his remarks, he suddenly began to babble incoherently.

"Let me close with this," the website quoted Biden as saying. "After I signed the pacandlpacatlackack into law, I handed the pen and I signed it with a wiszzfschuna, the most person most responsible for the legislation to a widow and her daughter of a late Sgt. First Class Heath Robinson."

Poll finds most voters don't think president is mentally fit

Additional video footage showed the president bizarrely attempting to advise young men on the sort of women they should marry.

"I say to every young man thinking of getting married, marry into a family with five or more daughters. I did. My wife is the oldest of five sisters," Biden declared.

"You know why? One of them will always love you, not the same one, but one of them will be on your side, that's the advantage of marrying into a family of five daughters," he added.

Biden's performance comes less than two weeks after a Harvard-Harris poll found that just 45% of registered voters believe he is "mentally fit to serve as president of the United States."

Nearly half of voters think Biden's condition is getting worse

While almost three quarters of Democrats felt the president has sufficient mental acuity to govern, that view was shared by just 20% of Republicans and 38% of independents.

When asked if they think Biden's condition is getting worse, staying the same, or improving, 47% indicated that they felt he is getting worse.

Meanwhile, 66% regard the president as being too old, a perspective which was held by 34% of Democrats, 91% of Republicans, and 77% of independents.
