At this writing, The Economist's readers prefer Obama 8,146 to 3.
No, that's not a typo, it really is a ratio of 2700:1.
I should point out, The Economist is a conservative newspaper.
Of course, as McCain's supporters would be quick to point out, their readership is almost exclusively highly-educated, well-read, and wealthy, not the sorts of people you'd want to hunt moose with. Good thing they're not running the world or anything.
