The people aren't happy. President Obama's approval rating has sunk to the lowest point yet, according to a new poll. Only 40 percent of the country thinks he's doing a good job, a NBC News/Wall Street Journal survey found. Seventy percent believe the country is heading in the wrong direction and six in 10 dissatisfied are with the economy. It isn't just Obama who's on the receiving end of America's discontent: 79 percent of respondents are displeased with the U.S. political system as a whole.
