On Tuesday, Sen. Barack Obama of Illinois will embark on a four-day campaign swing through Iowa, starting off with events that will mark the fifth anniversary of a speech he gave opposing the war at a rally in Chicago. His advisers have labeled it the "Judgment and Experience Tour," and Obama's success in persuading voters he has both may hold the key to his presidential aspirations.
"He looks back at his [Senate] primary election in 2004, when he was sitting comfortably in fourth place for a really long time," Gibbs said. "Then the campaign got fully engaged both on the ground and on TV. We all know what happened."
