WASHINGTON (AP) — This time, President Barack Obama says, he’s not budging. This is the confrontational Obama, the “Make my day” president, betting Republicans blink to avoid a government shutdown or a first-ever default of the nation’s debts.

It’s a proposition not without risk and one with a history of last-minute accommodations on both sides. Brinkmanship between Obama and congressional Republicans has often stopped at the precipice’s edge.
