On September 7, the International Olympic Committee will chose the host city for the 2020 Summer Olympic Games. The three candidate cities of Istanbul, Madrid and Tokyo will be voted on by about 100 members of the Olympic committee.

Each bidding city has its fair share of pros and cons heading into Saturday’s vote. 

Istanbul would become the first predominantly Muslim city to host the Olympics, which falls in line with the IOC’s mission to expose athletes and fans to new cultures and ways of life. The Olympics would find themselves in a region much different from the 2012 Olympics in London or the 2008 Olympics in China.

The country’s bid took a hit when antigovernment protests took place in June and then over 30 Turkish athletes were suspended for testing positive for performance enhancing drugs. The city responded to doping criticism by reaffirming their stance with a “zero-tolerance policy.” This will be Istanbul’s fifth bid.

Japan last hosted the Summer Games in 1964, when their bid won over Detroit. Tokyo appears to be the “crisis-free” bet for the Olympic committee. After the 2011 earthquake and tsunami, the country may be in need of a spirit lifter. The bid committee estimated that hosting the Summer Games would create more than 150,000 jobs and bring in $30.2 billion.

The biggest concern for organizers has been the Fukushima nuclear power plant disaster as a result of the earthquake, which continues to spill radioactive water into the ocean. Building a mile-long ice wall around the site of the power plant is one of the preliminary plans to solve the issue.

Third time is the charm? Madrid sure hopes so. The Spanish capital is a host city finalist after a third place finish for the 2012 Games and a second place finish for the 2016 Games. Spain last hosted the Olympics when Barcelona won the 1992 Summer Games over Paris.

Stadiums and venues are already standing and dozens of athletes have voiced their support for Madrid. The downside for Madrid comes from a more political standpoint as the country suffers from a jobless rate of 27 percent among its citizens. London hosted the 2012 Summer Olympic Games and some voters may see eight years as too soon of a return to Europe.

Whichever country leaves Buenos Aires victorious will have seven years to prepare for the Olympics.
