Even before this week, it was apparent Dick Cheney would not go gently into the not-so-good night of a former vice president, writes Ron Elving at NPR:

The man whom many consider the most powerful veep in history had already been far more vocal and visible than most of his predecessors in retirement. This week in particular, the former No. 2 has been out there almost daily, doing talk shows and giving a formal address to the American Enterprise Institute on the importance of interrogation techniques widely considered to be torture.

In other words, perfect Daily Show fodder.
