Biden's mix-up angers San Fran fans

Vice President Joe Biden managed to elicit boos at a Democratic fundraiser in San Francisco by declaring the Giants "are on their way to the Super Bowl."

The New York Giants and the 49ers will meet Sunday in San Francisco for the right to advance to Super Bowl XLVI in Indianapolis.

Biden's apparent show of support for the New York outfit drew some "good-natured" jeers from locals, according to a reporter from the Oakland Tribune — but Biden quickly backtracked, claiming he actually meant to say the 49ers but confused them with the city's baseball team, the Giants.

The event at the Bently Reserve, in San Francisco's financial district, reportedly raised between $275,000 and $1.1 million for President Obama's re-election bid, according to the Tribune.

Biden is on a West Coast fundraising swing, which includes stops Thursday in Reno, Nev., and Los Angeles.
