diving board vote
n.— «“It depends on what I call the diving board vote,” Clinton said. “In a lot of these districts there are people who have never voted Democrat before, but they want to…. They want to jump off that board and vote with us, but they’re still not quite sure. Over the next four days, the way these people turn will shape this election.”» —“Clinton stumps for Democrat friends in Arkansas” by Andrew DeMillo The Morning News (Arkansas) Nov. 4, 2006.
