Joe Biden

U.S. Vice President Joseph "Joe" Biden pauses during a speech on the final day of the DNC.

Vice President Joe Biden highlighted two major tests of his boss's first term -- the killing of al-Qaeda's founder and the bailout of the U.S. auto industry -- to argue President Barack Obama made "gutsy" choices that Republican Mitt Romney would not.

"He never wavers, he steps up," Biden said in his 38- minute address last night to the Democratic National Convention in Charlotte, North Carolina, before Obama's formal acceptance of his party's nomination to a second term.

Reprising one of his popular lines from the campaign trail, Biden summed up the meaning of those two decisions: "Osama bin Laden is dead and General Motors is alive."

In a message aimed at working-class voters and labor unions worried about jobs being shipped overseas, Biden also framed the contest between Obama and Romney as a choice between protecting U.S. workers or global corporate interests.
