U.S. government shutdown: What's next?

As the partial U.S. government shutdown enters a second day, and with both Republicans and Democrats firmly entrenched in their positions, any movement from either party to break the spending impasse seems unlikely in the days ahead.

"It looks pretty bleak to me," Matthew Baum, professor of public policy at Harvard University's John F. Kennedy school of government, said in an interview.
