Question

What us a Political Cliff? I am supposed to write a summary about the subject.

Answer 1

We hear much more about the fiscal cliff than a political cliff. I suppose the political cliff is the time when one or both parties act (or don't act) about an issue. At that point, the party feels it can't retreat.
