"He just locks down and can't get the words out," says one political consultant. "For such a fine speaker, it's really quite remarkable that he's had issues."
Obama's troubles with unscripted moments contributed to his campaign's refusal to participate in town hall format debates or discussions with Sen. John McCain, who feels much more comfortable in the unscripted moments.
