There's a broader decline worth noting, too. Trust in the executive and judicial branches were on the rise from the late 1970s until the late 1990s. It started to drop in the early 2000s. At a similar point, declining trust in the legislative branch started to dip more severely after a period of improvement.
Gallup notes that trust in government jumped after the 2012 Democratic National Convention. So the drop in the year since could reflect a natural wane in enthusiasm after a surge keyed to a specific event.
The reality is that as the government is dealing with crucial domestic and foreign policy issues such as Syria, the debt limit and funding the government, to name a few, the American public isn't overwhelmingly saying, 'Hey, we're confident you guys are going to work this all out.'
And it could be getting worse for the government's public image, considering what's at stake.
"If the federal government is unable to pass a federal budget to avoid a government shutdown, or reach an agreement to raise the federal debt limit in the coming weeks, trust is likely to continue to erode further," concludes Gallup.
It's a reminder that what happens in Washington in the coming weeks could speak volumes about the way Americans perceive their government only about a year from the midterm elections.
