The yes vote for Scotland leaving the United Kingdom has gained significant ground on the no vote, just a little more than two weeks ahead of the referendum, new data show. A YouGov poll shows 47 percent saying they will vote to quit Britain and 53 percent claiming they will vote for continued unity. As recently as mid-August the no campaign was leading by 14 points, and by as much as 17 points in June. The poll showed that the gretest change has come among Labor Party voters. Thirty percent of those now say they will vote yes, compared with 18 percent a month ago. The Scottish referendum is September 18, and now looks as if it will go down to the wire.
