Speaking to a South Carolina crowd just days before the state's primary election, former Vice President Joe Biden mistakenly told the audience he was a Democratic candidate for the United States Senate.
"I have a simple proposition here," Biden said. "I'm here to ask you for your help. Where I come from, you don't get far unless you ask. My name's Joe Biden, I'm a Democratic candidate for the United States Senate. Look me over, if you like what you see, help out. If not, vote for the other Biden. Give me a look though, ok?"
South Carolina is a state where Biden has been the clear favorite for months, but an NBC News/Marist poll from Monday has his lead over Senator Bernie Sanders down to 4%.
South Carolina's primary is Saturday.
According to the Associated Press, through three states so far, Sanders has the most delegates with 45, Pete Buttigieg is second with 25 and Biden is in third with 15.
South Carolina is the last state with a primary before Super Tuesday, where 14 states plus American Samoa cast their votes.
The Democratic candidates will debate Tuesday night ahead of the South Carolina election.
