Politicians' Placemark PopularityAs is par for the course around here, each color dot represents more references in that location to the name of that politician than to each of the other seven. In other words, a purple dot means that there are more references to Barack Obama than to Angela Merkel, David Cameron, etc. It should also be noted that the keywords used for this comparison are the full names of each politician, rather than simply a last name.
Politician's Popularity in Europe
Where this map gets interesting, however, is when one looks away from Europe, especially returning to the United States (see the first map above). One may expect a veritable blanket of purple, symbolizing Obama, to cover the country in much the same way as the references to other political leaders did in their home countries. It is instead a potpourri of colors, with each of the other politicians dominating in one place or another. Whether this has to do with Obama's declining popularity or something else, we are unsure.
Given that all of the other countries included in this map, with the exception of Russia, are relatively small in terms of area, there may be a negative correlation between the areal extent of the country and the likelihood of complete homogeneity in Google Maps references. It is surprising, however, how much this deviates from Obama's dominance when compared to John McCain in 2008, as reflected in our Presidential Placemark Poll map. Maybe this is just evidence of an evil Obama plot to sell off America's virtual territory to socialist (and not-so-socialist) Europeans?
As always, our speculation usually leads us to a dead end, to which we have now arrived. Let the digital jockeying for territorial dominance commence!
