PRINCETON, NJ — U.S. President Barack Obama begins his second term at a time when Americans are as negative about the state of the country and its prospects going forward as they have been in more than three decades. Fewer than four in 10 Americans (39%) rate the current status of the U.S. at the positive end of a zero to 10 scale. This is about the same as in 2010, but it is fewer than have said so at any point since 1979. As they usually are, Americans are more upbeat in their predictions of where the U.S. will be in five years (48% positive), but this is also lower than at any time since 1979. Fifty-five percent of Americans say the state of the nation five years ago was positive.
