Thanks to a scandal that has left veterans to die without care and the agency under investigation, the Department of Veterans Affairs is the federal government's most hated agency.

The percentage of Americans with a favorable view of the VA rose from 57 percent to 68 percent from March 2010 to October 2013, according to Pew Research Center. Today, that percentage has plummeted to 39 percent. That's the lowest of any federal agency, and marks the biggest decline from October 2013 to the present.

The most popular federal agencies are the United States Postal Service, the National Park Service, the Centers for Disease Control and Prevention and NASA. All four agencies enjoy more than 50 percent net favorability.

The IRS, the Department of Education and the Department of Justice all join the VA on the more-disliked end of the spectrum. Each agency has a negative favorability rating.

Scandals appear to have damaged the VA harder than the IRS. Despite possible discrimination against conservatives, the IRS has only fallen from 47 percent favorability to 42 percent from March 2010 to the present. The IRS was the most-hated federal agency in October 2013. It has since "improved" to the second most-hated, but its favorability has still declined by two percentage points since then.
