And the pendulum swings, again. A new poll on Scottish independence puts the vote against leaving the United Kingdom ahead by six points--about where things were two months ago, before the yes vote surged slightly ahead in recent days. The new poll was conducted by Survation between September 5 and 9 and covered 1,000 Scottish residents. The bump comes just as British Prime Minister David Cameron and other London-based politicians, some of whom have been reported as "panicked" over the September 18 referendum, have been visiting Scotland and pleading with the Scots not to leave the 300-year-old union. Cameron noticeably abandoned any "fear-factor" tactics and instead delivered impassioned, personal pleas for Scotland to stay.
