When praising words overwhelm Alan Greenspan, Harry Reid, the Senate
minority leader, instead said, "I'm not a big Greenspan fan. I think
he's one of the biggest political
hacks we have in Washington."
Is "hack" here a derogatory term? Or just means someone who is
employed, like a hackney? I guess it's a derogatory word, because the
article continued,
"His harsh comment was politely overlooked in governing circles, like an
off-color joke told at a Washington dinner party."
So, what exactly is "off-color"? Where'd it originate from?
Thank you.
