“The motion is adopted. Without objection, the motion to reconsider is laid on the table.” Here we are again. Partisan political bickering has led to another government shutdown. But what does that mean? The federal fiscal year starts on Oct. 1, often without new spending laws in place. Instead, the president and Congress strike a short-term deal to buy more time. If they can’t reach a new agreement before the next deadline, much of the federal government shuts down. Since October, there have already been three short-term agreements. When the government shuts down, federal workers are either forced off the job or told to work without pay. Essential services, such as airport security and food inspections, stay in place. The military remains active but may not be paid on time, depending on how long the shutdown drags on. And national parks and monuments will remain open, at least this time. In the event of a shutdown, the I.R.S. will likely be forced to slow implementation of the new tax bill. Funding for Puerto Rico, still rebuilding from Hurricane Maria, also hangs in the balance. The future will remain unclear for DACA recipients. And without an extension, the Children’s Health Insurance Program will run out of money.
