As a physician who heads a financial planning company and prides herself on having read every page of President Obama’s health care reform bill, Ms. McClanahan, 47, recognized that it’s not every day you’re seated next to a presidential candidate on a two-hour flight. According to Ms. McClanahan, about an hour into the flight — which Mr. Romney mostly spent reading USA Today and using an iPad while wearing headphones — she told him her idea for improving the American health care system: slashing overhead costs by switching to an electronic billing system.

“He looked at me blankly and said, ‘I understand,’ then put his iPad headphones in and kept reading,” she said.

While Ms. McClanahan said Mr. Romney was likely exhausted, she was disappointed he showed so little interest. Even another passenger’s request for a restaurant recommendation in Boston elicited little from Mr. Romney, she said. “I can’t give you any,” he said, according to Ms. McClanahan. “You’ll have to ask someone else.”…

“I feel he’s out of touch or doesn’t want to be in touch or that he’s afraid to be in touch,” she said. “He’s just like people describe him: just very wooden.”
