(CNN) One man at the rally said he was "scared of an Obama presidency." McCain later told the man he should not fear Obama.
"I want to be president of the United States, and I don't want Obama to be," he said. "But I have to tell you, I have to tell you, he is a decent person, and a person that you do not have to be scared [of] as president of the United States."
McCain's response was met with boos from the crowd.
