After joking about the extended Democratic primary season – “I was planning to run for the '08 election, not the 2012 election!" – Obama responded to some vocal Clinton critics in the crowd, who had reacted to praise for the senator from both the presumptive Democratic nominee and Michigan Gov. Jennifer Granholm, a longtime Clinton supporter.
"I want everybody here to be absolutely clear - I want everybody here to be absolutely clear - Senator Clinton is one of the finest public servants we have in American life today," said Obama, noting her work on behalf of children's rights and universal health care.
"She has been on the right side of just about every battle that we have fought - she has, in her own words, shattered a glass ceiling into 18 million pieces. ….She is worthy of our respect, she is worthy of our honor.
“…And she's tough! That's why this race took so long. She's a fighter and we need fighters in the Democratic Party. Because we've got a lot to fight for. There's a lot worth fighting for.”
Gore, who remained neutral throughout the primary season, made his first campaign appearance for Obama at the Detroit rally. "Take it from me, elections matter," said the 2000 Democratic presidential nominee. "After the last eight years, even our dogs and cats have learned that elections matter."
He compared Republican criticism that Obama is unexperienced and naïve to Nixon's attacks on John Kennedy in 1960. "I know what [Kennedy's] inspiration meant to my generation, and I feel that same spirit in this auditorium here tonight, building all over this country this year," said Gore.
