Obama is reported to be considering Sen. Jim Webb of Virginia and former Sen. Sam Nunn of Georgia, two Democrats with formidable national security credentials, but he's more likely to settle on Sen. Joseph R. Biden Jr. of Delaware or Sen. Evan Bayh of Indiana.
Sen. Hillary Rodham Clinton of New York, who battled Obama for the nomination, is not likely to be chosen, Democratic strategists have concluded -- if only because her husband, former President Clinton, has conspicuously failed to make peace with the man who defeated his wife.
For The Record

Potential running mates: A graphic in Monday's Section A that accompanied an article on potential 2008 vice presidential candidates said Sen. Joseph R. Biden Jr. (D-Del.) had criticized Barack Obama, the presumptive Democratic presidential nominee, for offering to meet with the leaders of North Korea and Iraq. Obama had offered to meet with the leaders of North Korea and Iran.
To go with such analyses, here are some facts:
Geography is not as important as it used to be. The last vice presidential candidate chosen mainly to deliver a state's electoral votes was Lyndon B. Johnson of Texas, and that campaign was in 1960, a year before Obama was born.
Instead, each of the current campaigns is probably asking four questions, strategists from both parties said.
First, does the candidate bring balance to the ticket -- not geographical balance but resume balance? McCain probably wants someone who can shore up his standing among social conservatives, the Republican "base" that provides millions of volunteers and voters but has been relatively unenthusiastic about him. Obama may be looking for someone with deeper national security experience than a first-term senator who didn't serve in the military.
Second, credibility: "Is this someone who could, in an emergency, step in and lead the nation?" Durbin asked. That question is as important for Obama, 46, as it is for McCain, 71.
Third, compatibility: Can these two politicians forge a good working partnership that will make their campaign more effective? And in an era when the vice presidency has become more powerful than ever before, could they work well together in the White House?
"What both Sen. Obama and Sen. McCain will be looking for is someone who will be a partner in governing," said Ron Klain, who helped Democratic nominee Al Gore choose Lieberman as his running mate in 2000.
"Outside observers assume it's a more political decision than it is."
Finally, there's the "do no harm" rule: Will the vice presidential nominee turn out to be a problem instead of an asset? In 1972, Democratic vice presidential nominee Thomas F. Eagleton withdrew from the race after a newspaper discovered that he had received psychiatric care, including electric shock treatments.
