Dissatisfied

Gallup reports:

In 2016, an average of 27% of Americans have been satisfied with the way things are going in the U.S. This is comparable to averages since 2012 but is lower than the 37% yearly average over the 37 years Gallup has tracked this measure.

In the recent trend, 2006 was a transitional year; satisfaction dropped nine percentage points from the previous year, coinciding with Americans' decreasing approval of then-President George W. Bush and an increase in their belief that the Iraq War was a mistake. Lower satisfaction levels in 2006 likely contributed to the Democrats taking control of the House of Representatives for the first time in 12 years. Before 2006, the yearly average satisfaction level for the previous 26 years measured was 42%.
