shifting tide?

From Balloon Juice, an interesting map showing voting shifts by county between 2004 and 2008. I was surprised by the implied prevalence of blue in the first place - there is only one state filled with counties that are dark blue, which tells me most weren't blood red to begin with. I'm not discounting the notable shifts to blue (20%+), just noting that the degree of the shift in most cases wasn't huge (10-19%), which is both reassuring and not: it's nice to know the country as a whole is more moderate than it can sometimes feel, but I hope we're not a small shift back to pink that undoes any good that will be done in the next four years.

Anyway, check out the accompanying post at Balloon Juice.
