Senator John McCain's presidential campaign was quick to pounce on Sen. Barack Obama when he introduced his running mate, Joe Biden as the "next president."
Obama said: "So let me introduce to you the next President -- the next Vice President of United States of America, Joe Biden!"
"Barack Obama sounded as though he turned over the top spot on the ticket today to his new mentor, when he introduced Joe Biden as the next president," a McCain press release said. "The reality is that nothing has changed since Joe Biden first made his assessment that Barack Obama is not ready to lead. He wasn't ready then and he isn't ready now."
