Former Vice President Joe Biden made yet another gaffe Monday, saying in a South Carolina campaign speech that he is a “candidate for the United States Senate” and that people could “vote for the other Biden” if he is not their preferred presidential candidate.

“My name is 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,” the 77-year-old said in his remarks at the First in the South Dinner, according to a video that has gone viral on Twitter.

The pair of confusing statements comes as Democrat primary candidates will debate Tuesday evening in Charleston. The Palmetto State will head to the polls for its primary contest on Saturday, where Biden hopes to use his “firewall” to blunt Sen. Bernie Sanders’s (I-VT) momentum after winning the Nevada caucuses. Earlier this month, the Vermont senator won the New Hampshire primary and took the popular vote in Iowa. A Public Policy Polling survey released Monday shows Biden with 36 percent of support, while Sanders is trailing in second at 21 percent.

Biden is no stranger to making confusing statements on the campaign trail. Biden referred to New Hampshire as Nevada on the night of the Granite State’s primary. The incident was one of several in which he has appeared confused about the city or state that’s he’s campaigning in.

Appearing Thursday at a CNN town hall event, Biden said deceased son Beau Biden, who served as the Attorney General of Delaware, was the U.S. Attorney General.
