From the start, it has seemed like the federal government shutdown with no end in sight. More than three weeks later, with Washington still gridlocked over President Trump’s demand for a wall along the southwestern border, that is still true.

But the sharpest effects of the longest shutdown in the nation’s 242-year history are only beginning to emerge across the country. In many parts of the United States, the shutdown has underscored how deeply the federal government is connected to everyday life, and the spending standoff has created cascading crises far from the border.

About 800,000 federal workers are going without pay — and a growing number of them, worrying about missing mortgage and credit card payments, are filing for unemployment benefits. Thousands more federal contractors are off the job and will most likely not be able to recoup their missed paychecks. Restaurants and shops near major federal offices, especially in Washington, have emptied out.
