Only 19% of Americans today say they can trust the government in Washington to do what is right “just about always” (3%) or “most of the time” (16%). Fewer than three-in-ten Americans have expressed trust in the federal government in every major national poll conducted since July 2007 – the longest period of low trust in government in more than 50 years.

interestingly it went way up after 9/11 I would have expected the opposite.
