How about this question?
David Brooks, approving of ABC's debate, writes
"... I thought the questions were excellent. The journalist’s job is to make politicians uncomfortable, to explore evasions, contradictions and vulnerabilities. Almost every question tonight did that."
Taking that as a standard ("make politicians uncomfortable"), why not ask:
Which hand do you use when you wipe your ass?
I wonder if Brooks has ever made George W uncomfortable? Or any other republican? His columns in the past couple of years are from the botton of his barrel as it is difficult even for him to say anything positive about George W.
