Former Vice President Joe Biden’s poll numbers have plummeted to new lows following his widely panned performance in last week’s debate.

Biden was polling at 27 percent in the RealClearPolitics polling average as of Tuesday evening –Biden’s lowest average since launching his campaign in April, and well below his peak at 41 percent in May.

The most recent polls following last Thursday’s debate show Biden dropping even further.

A CNN poll released Monday and a Quinnipiac poll released Tuesday both showed Biden at 22 percent — lower than he’s been in either poll since his campaign began.

Both polls show Biden, whose lead was already shrinking going into the debate, only narrowly edging out Democratic California Sen. Kamala Harris.

Harris is surging in the polls after attacking Biden in the debate for his opposition to forced desegregation busing in the 1970s.

“I do not believe you are a racist. And I agree with you when you commit yourself to the importance of finding common ground, but I also believe and it is personal and it was actually hurtful to hear you talk about the reputations of two United States senators who built their reputation and career on the segregation of race in this country and it was not only that but you also worked with them to oppose busing,” she told Biden on Thursday.
