"Up" is an industrious little word, always looking for new ways to make itself useful.
From the cover piece in today's New York Times Magazine, quoting a member of John McCain's inner circle:
"So the thinking was, do you man up and try to affect the outcome, or do you hold it at arm's length? And no, it was not an easy call."
From Dahlia Lithwick in Slate yesterday:
It's become a truism of elections that both camps will "lawyer up" before the big day.
"to request a lawyer when being questioned by the police, often implying a probable lack of cooperation with the investigation."
