"executive activism"

check out this piece from slate. good analysis of the broader significance of the NSA scandal within the administration's outlook on division of power. also has a good summation of the bush approach to decision-making:

Bush and Cheney had their own reasons for presidential power building. Both men were CEOs who equated impatience with efficiency, and envisioned a don't-bore-me-with-the-facts, CEO-style presidency.

the "legacy" article is also good, touching on related stuff.
