That second-link above, indicates that from General Election to General Election, Edinburgh has seen:
- a 3.1% drop in Lib-Dem support
- and a 4.1% increase in Labour support
--- which means the gap between the two has gone from:
- 1.4% in 2005
- to 8.6% in 2010
That's right - the gap has increased more than six-fold in five-years.
