cut the turf
v. phr.— «Some of our targeted homeowners are suspicious. Some refuse to come to the door. Others hide behind twitched curtains until we leave. We are like political Jehovah’s Witnesses, but we are unrepentant. And, were we to falter, back at West Denver’s Obama HQ hand-painted signs urge us to keep up the canvassing—or “cutting the turf,” as they call it—to help save America.» —“Barack Obama’s campaign machine kicks into gear” by Tom Whipple Times (London, United Kingdom) Oct. 27, 2008.
