"Senator Obama's confidence has grown as his political successes have grown," said Ed Dorn, a professor at the University of Texas LBJ School of Public Affairs. But Dorn said the candidate had not gone too far with his attitude. "I see no evidence that he's making a leap toward arrogance," he said. The confidence is clear throughout Obama's campaign staff. Campaign manager David Plouffe poured scorn on Clinton's chances as he discussed the stakes for the Texas and Ohio primaries. "The Clinton campaign needs to begin winning big states with big margins to have any hope," he told reporters in a conference call on Friday. "They are going to fail on that measure and fail miserably."
