As a Democratic presidential candidate, when Obama talked about health care, wars in Iraq and Afghanistan, the snowballing recession, spiraling college tuition, and the home mortgage crisis, crowds cheered. Yet now barely a year into his term, people expect repairs to have happened with speed equal to that of the Internet. A handful of presidents from Lincoln to Roosevelt to McKinley have inherited similar societal hairballs, said James Hilty, a Temple historian and a nationally published presidential scholar. “It’s a very different environment today,” said Hilty. “I’ll blame the 24-hour news cycles. But I also blame the basic immaturity of the country. We want something, and we want it right now. And the people who have the most outlandish things to say get the most attention.”
