McCain has made up ground on the economy in this survey, from -15, to -8.
I think it’s a mistake for him to try any sort of shift to national security. By a huge margin, the economy is the most important issue and McCain appears to have some traction of late. He has to keep at it until the end.
Here is a website with the sampling data.
Fox News changed the sampling from last week D43, R37 to D41, R39 this week. It looks like McCain has improved some, but a bit is overstated because of the change in the sampling.
