We know already what the general outcome would be, given Obama's popularity outside USA, but still, interesting initiative from The Economist. Can you guess which country will have the highest proportion of Blue votes; France looks like a strong candidate, as of now. (The reverse question is much more interesting).
PS. Obviously one needs to take into account all kinds of selection and measurement issues, but let us ignore those for the moment and assume, e.g., that readers of The Economist are a random sample of the population of each of those countries :-)...
