Obama Formally Enters Presidential Race

“If a campaign is premised on personality, then no, I don’t think you can stay fresh for a year,” he said. “But if the campaign is built from the ground up and there is a sense of ownership among people who want to see significant change, then absolutely. It can build and grow.”
And in his speech here on Saturday, Mr. Obama, trying to offer himself as the grass-roots outsider in contrast to a member of a political family that has dominated Washington life for 15 years, presented his campaign as an effort “not just to hold an office, but to gather with you to transform a nation.”
“That is why this campaign can’t only be about me,” Mr. Obama said. “It must be about us. It must be about what we can do together.
