Barack Obama introduced Sen. Joe Biden of Delaware Saturday as a man "ready to step in and be president," and the newly minted running mate quickly turned his campaign debut into a slashing attack on eight years of Republicans seeking four more years in the White House. John McCain would have to "figure out which of the kitchen tables to sit at" when considering his own economic future, said Biden, jabbing at the man he called his personal friend.
It was a reference to McCain's recent inartful admission that he was not sure how many homes he owns.
Before a vast crowd spilling out from the front of the Old State Capitol, Obama said Biden was "what many others pretend to be - a statesman with sound judgment who doesn't have to hide behind bluster to keep America strong."
Democrats coalesced quickly around Obama's selection of the 65-year-old veteran of three decades in the Senate - a choice meant to provide foreign policy heft to the party's ticket for the fall campaign against McCain and the Republicans.
Obama made a symbolic choice for the ticket's first joint appearance. It was a brutally cold winter day more than a year ago when he stood outside the historic structure in the Illinois capital to launch his quest for the White House.
He returned in sunshine, the party's improbable nominee-in-waiting, a 47-year-old black man who outdistanced a crowded field of far better-known and more experienced rivals.
Thousands of newly printed signs bearing the words Obama/Biden sprouted in the crowd that waited in anticipation in 90-degree temperatures.
Obama's remarks were carefully crafted to emphasize Biden's accomplishments in the Senate, his blue-collar roots and - above all - his experience on foreign policy.
"I can tell you Joe Biden gets it," he said. "He's that unique public servant who is at home in a bar in Cedar Rapids and the corridors of the Capitol, in the VFW hall in Concord, and at the center of an international crisis," he said.
Obama recounted the personal tragedy that struck Biden more than 30 years ago, within days of his election to the Senate, when his first wife and their child were killed in an automobile accident.
He said Biden raised his surviving children as a single parent, commuting between the Capitol and Delaware daily on the Amtrak train.
"For decades, he has brought change to Washington, but Washington hasn't changed him," Obama said, attempting to blunt an emerging Republican line of attack that notes Biden's 30 years in the polished corridors of the Capitol.
"He's an expert on foreign policy whose heart and values are rooted firmly in the middle class."
Obama brought Biden on stage with his rousing introduction to the strains of Bruce Springsteen's "The Rising."
The newly named running mate moved center stage in shirt-sleeves at a brisk 65-year-old man's trot, embracing Obama.
"I'm glad to be here," he said.
The loquacious Biden spoke at least as long as Obama, who at one point he called "Barack America."
