I think all the serious presidential contenders should sit down for a game of Diplomacy. Each candidate should be matched up with the country most appropriate to their personality and style of politics. For example,
Austria: Bernie Sanders. A massive underdog at the beginning but has the potential to be a dominant force if left alone for too long. Much like Austria can easily grab Serbia but has to fight for any other centers, so too has Sanders already grabbed his low hanging fruit supporters (basically anyone on reddit) but will need to actively campaign to make any meaningful gains. Will definitely need support into Iowa.
England: Jeb Bush. Much like the English aristocracy, Bush is blessed with a long bloodline of royalty. Unfortunately, the relevant antecedent British monarchs for Bush are Richard III and a latter day George III. Is also overrated as a power.
France: Scott Walker. Like Wisconsin in recent years, Walker has had troubles with public sector unions. This makes him a perfect French player, whose unions are notorious for going on strike.
Germany: Donald Trump. Likes to push people around and plays well from a position of power. Also has an historical track record of bankruptcy and anti Semitism.
Italy: Marco Rubio. Like Italy, Rubio hails from a similarly peninsular state. Like Florida, Italy is filled with bad drivers and overrun with illegal immigrants.
Russia: Hillary. Already has a leg up on the competition, much like Russia's fourth home center. Unfortunately for the rest of the field, Hillary got a ten year head start and already holds all Balkan centers, Scandinavia, the Black Sea, and only needs one center to win.
Turkey: Rand Paul. Much like Turkey in the actual game, he's very difficult to eliminate. Much like Turkey historically, its very difficult to figure out how its considered to be a European power. Speaking of Turkish history, some Biblical scholars theorize that the great flood of Genesis may have been the Black Sea breaking through the Dardanelles. Which makes sense for Rand Paul, because he's going to need a fucking miracle to win.
