Americans are not confident that the government can protect the data it collects on them and are increasingly wary of overreaching surveillance practices, according to a new poll.

The survey, conducted by the Pew Research Center, found that just 6 percent of American adults are “very confident” that the government can keep their data secure. The same meager percentage said they were “very confident” that telephone companies can do the same.

In addition, respondents said they have a “pervasive sense” that they are being watched in their public and private lives. They also feel that they have very little control over the data that is collected and stored about them and how it is used.

The new numbers, which show that Americans overwhelmingly value their privacy, come as Congress is under pressure this week to reauthorize or amend Section 215 of the Patriot Act, a provision that legally justified government surveillance conducted by the National Security Agency. Nearly two years ago, then-NSA contractor Edward Snowden revealed the existence of the agency’s bulk telephone data collection programs; that disclosure has since been used as fodder for civil liberties advocates to promote privacy and Fourth Amendment rights.

“In the almost two years that have passed since the initial Snowden revelations, the public has been awash in news stories detailing security breaches at major retailers, health insurance companies and financial institutions,” Mary Madden, a senior researcher at Pew, said in a press release. “Many find these developments deeply troubling and want limits put in place, while some do not feel these issues affect them personally.”

Though Senate hawks are pushing for a “clean” renewal of the 2001 law, which all but one member of the upper chamber voted for at the time, Sen. Rand Paul, a presidential candidate and vocal opponent of the NSA’s bulk data collection, has said he would do “everything humanly possible” to prevent the reauthorization of Section 215. This includes, the Kentucky Republican said, a potential filibuster of the measure, which needs 60 votes to advance. The law expires on June 1, and with Congress on recess next week, only days remain to reach an agreement.

On the issue of government surveillance, Democratic Sen. Ron Wyden shares the stance of Paul and other libertarian-leaning Republicans who are working to defy Senate Majority Leader Mitch McConnell.

Even after a federal appeals court deemed the surveillance programs illegal, the senior senator from Kentucky made clear he supports the extension of Section 215. McConnell has since introduced a measure that would temporarily extend it for two months to allow for more debate.

Complicating matters for McConnell’s camp, the Pew survey also found that 65 percent of Americans believe there are not any appropriate limits on “what telephone and Internet data the government can collect” when it comes to counterterrorism efforts.

“Contrary to assertions that people ‘don’t care’ about privacy in the digital age, this survey suggests that Americans hold a range of strong views about the importance of control over their personal information and freedom from surveillance in daily life,” Madden and Pew colleague Lee Rainie wrote.

Despite these concerns, though, 91 percent of respondents said they have not made any changes to their cellphone or Internet practices.

The House of Representatives overwhelmingly passed the USA Freedom Act last week, which would institute reforms to the Patriot Act and effectively end the bulk data collection. Many lawmakers who rejected that measure, however, did so because they thought it did not go far enough to curb the NSA’s surveillance and data collection powers.

On Tuesday, Rep. Adam Schiff pressured the Senate to bring the USA Freedom Act to a vote, saying he does not believe there would be enough votes in the House to pass the short-term extension proposed by McConnell.

Schiff, the top Democrat on the House Intelligence Committee, predicted significant bipartisan support for the USA Freedom Act in the upper chamber, and said even those in the House who want a clean reauthorization “could see the writing on the wall and were supportive of USA Freedom as sort of the next best thing.”

McConnell said he intends to hold a vote this week on the reauthorization of Section 215. He also said he will put the USA Freedom Act up for a vote, but it isn’t yet clear whether it has the 60-vote support required to end debate.

The Pew survey was conducted separately in two different increments. The first sampled 498 adults between August and September 2014, and has a margin of error of plus or minus 5.6 percentage points. The second survey polled 461 adults between January and February 2015, and has a margin of error of plus or minus 5.8 percentage points.
