I put together a little chart looking at ten prominent "battleground states" to see what the last month or so has meant for the poll numbers. (Positive numbers = Obama lead; negative numbers = Romney lead).
It certainly looks like there has been a lot of erosion of support for Obama, doesn't it?
(Note: There has been no recent data released for North Carolina as Obama is no longer viewed as being competitive in the state. I used the latest available data, October 18th, for the later North Carolina average. All data gleaned from Real Clear Politics.)
As a point of comparison, here are the current poll numbers compared with the actual results of 2008.
Many of the "predictive models" have been assuming 2008 levels of enthusiasm for Obama in the tailoring of their samples. However, its difficult to see that enthusiasm when you look at the numbers.
