Among the survey's findings:
— Sixty-eight percent said the shutdown is a major problem for the country, including majorities of Republicans (58 percent), Democrats (82 percent) and independents (57 percent).
— Fifty-two percent said Obama is not doing enough to cooperate with Republicans to end the shutdown; 63 percent say Republicans aren't doing enough to cooperate with him.
— Republicans are split on just how much cooperation they want. Among those who do not back the tea party, fully 48 percent say their party should be doing more with Obama to find a solution. But only 15 percent of tea-party Republicans want that outreach. The vast majority of them say GOP leaders are doing what they should with the president, or should do even less with him.
— People seem conflicted or confused about the showdown over the debt limit. Six in 10 predict an economic crisis if the government's ability to borrow isn't renewed later this month with an increase in the debt limit — an expectation widely shared by economists. Yet only 30 percent say they support raising the limit; 46 percent were neutral on the question.
In Mount Prospect, Ill., Barbara Olpinski, 51, a Republican who blames Obama and both parties for the shutdown, said her family is already seeing an impact and that will worsen if the impasse goes on. She's an in-home elderly care director, her daughter is a physician's assistant at a rural clinic that treats patients who rely on government coverage, and her husband is a doctor who can't get flu vaccines for patients on public assistance because deliveries have stopped.
"People don't know how they are going to pay for things, and what will be covered," she said. "Everybody is kind of like holding their wallets."
Moore traveled to Las Vegas with his wife and Florida relatives hoping to see Red Rock Canyon, only to find the national conservation area closed. Instead they went to Hoover Dam, also a federal property but one that has remained open because it is not financed with congressional appropriations. "Not a catastrophe," he said, but he doesn't know when they'll go again.
The AP-GfK Poll was conducted Oct. 3-7 and involved online interviews with 1,227 adults. The survey has a margin of sampling error of plus or minus 3.4 percentage points for all respondents.
The survey used GfK's KnowledgePanel, a probability-based Internet panel designed to be representative of the U.S. population. Respondents to the survey were first selected randomly using phone or mail survey methods, and were later interviewed for this survey online. People selected for KnowledgePanel who didn't have online access were given that access at no cost to them.
