“I support defunding Obamacare. I think Obamacare is a disaster. When they say government shutdown, it doesn't mean that everything is going to stop,” said Larry Green, a tour industry worker.

And some prefer not to follow the news in Washington.

"Not as much as I should, I admit, and I probably represent quite a few people. But about the budget impasse, I think it happened so many times before,” said Julie Mammano, a children's author.

With fiscal showdowns common, some Americans may shrug at Washington’s current impasse. But that will change if the federal government closes on October 1, according to analyst Stan Collender.

“This will start to have an impact on people’s thinking when it has an impact on their lives - not when they are hearing about the possibility on the news, but when they call the Department of Education and no one is there to answer the phone. Or when they need a visa or a passport and no one is there to process it," said Collender.

Collender thinks this time a shutdown is more likely than not, and that Americans are suffering from what he calls “crisis fatigue.”

No one should underestimate consequences of a shutdown, according to Democratic Senator Charles Schumer. “I think the American people get very aware when the stock market goes down 2,000 points.”

In New York, some urge consequences for members of Congress. "I think they should all be fired,” said Linda, a visitor to New York.
