Democratic presidential front-runner Joe Biden says it would be �great� to have a female vice president, but he won�t say whether he�d pick Sen. Kamala Harris for the No. 2 spot if he receives his party�s nomination.

In an interview aired Friday on CNN, Biden said, �I think it helps having a woman on the ticket.� He was asked whether it might be Harris, who confronted him at last week�s Democratic presidential debate over his stance on busing in the 1970s. He said he was not going to get into specifics because �I don�t even have the nomination.�

�I think it�d be great to have a female VP,� Biden said. �And if I don�t win, it�d be great to have a female president.�

Harris surged in polls after the debate confrontation , when she criticized Biden for recently highlighting his decades-old work with segregationist senators and his opposition to public school busing during the 1970s.

The former vice president is leading the pack of more than 20 Democratic presidential hopefuls .

Biden is considered a moderate at a time in which some in the party, including presidential hopefuls Sens. Elizabeth Warren and Bernie Sanders, are pushing it further left on economic and social issues.

Biden insisted that the �vast majority of Democrats are where I am on issues,� and he called the party �center-left.�

�Look, it�s center-left,� he said. �That�s where I am. Where it�s not is way left.�
