The "Global" Electoral College, compliments of The Economist

The Economist has launched a website called “The Global Electoral College”. How this actually works is described in an article on economist.com entitled “Global Electoral College, Obama or McCain, who do you want?“: The Economist has redrawn the electoral map to give all 195 of the world’s countries (including the United States) a say in the election’s outcome. As in America, each country has been allocated a minimum of three electoral-college votes with extra votes allocated in proportion to population size. With over 6.5 billion people enfranchised, the result is a much larger electoral college of 9,875 votes. But rally your countrymen—a nation must have at least ten individual votes in order to have its electoral-college votes counted. There are few countries whose votes in the Global Electoral College are a foregone conclusion. So the winner is unlikely to be decided by a small number of “swing countries”. Rather, they will have to cobble together a coalition of small, medium and large nations. (A campaign stop in Beijing is recommended, as well as a tour of Africa.) Voting in the Global Electoral College will close at midnight London time on November 1st, when the candidate with most electoral-college votes will be declared the winner.” What this online poll reveals more than anything else are the political preferences of Economist subscribers from all around the globe. Apparently with that group, McCain isn’t particularly popular, since the latest tally is 8,192 global electoral college votes for Obama, and only 3 for McCain. So far, no Iraqis or Iranians have registered their votes online, so Obama and McCain are tied at 0% in both of these countries. However, Obama has an 83/17 edge right now in Afghanistan, which is pretty close to his 79/21 “lead” in the United States. The only country in the world right now which is pro-McCain is Andorra (62/38 in favor), which is the current source of McCain’s 3 global electoral college votes!]]>
