"When candidates are running for office, they try to come up with a slogan that will be catchy and also inspirational. When Mr. Obama, then a U.S. senator, was trying to become president in 2007-2008, he and his campaign created the "yes we can" slogan to represent that we (the American people) can make changes, get get things done, can do more than we thought we would be able to do."
He used it at the end of his 2004 senatorial victory speech in Illinois and indicated there that it had been used since the start of that campaign. The exact wording is, "I have three words for them. What are those words? Yes, we can."
Barack Obama first said "yes we can" in a speech on January 8, 2008, while campaigning for the Democratic presidential nomination. The phrase became a key slogan for his campaign and a rallying cry for his supporters throughout the 2008 presidential election.
