Former Vice President Joe Biden made another blunder while giving a speech to South Carolina voters ahead of this weekend's primary.

During the South Carolina Democratic Party's First in the South Dinner, Biden, who was reportedly greeted by the longest standing ovation in the dinner's history, made the error as he was concluding his remarks.

"You're the ones who sent Barack Obama the presidency. And I have a simple proposition here: I'm here to ask you for your help," Biden asked of the audience. "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?"

Biden, who was a Delaware senator from 1973 to 2009, performed poorly in the first three contests for the Democratic nomination for president. His best performance so far was in Nevada, where he got second place with 19% of the vote. While addressing supporters at the conclusion of Nevada's caucuses, Biden took several shots at Vermont Sen. Bernie Sanders, who recently cemented his front-runner status in the Democratic field, and former New York City Mayor Michael Bloomberg.

“I ain’t a socialist, I ain’t a plutocrat — I’m a Democrat — and proud of it,” Biden said. "And I promise you, I wasn’t talking about running in the Democratic primary against him in 2012," he added, referring to former President Barack Obama.

According to the RealClearPolitics polling average, Biden, 77, holds the lead before Saturday's South Carolina primary with approximately 27% support.
