Interesting report from mexican IOC member Olegario Vázquez Raña; EL PAÍS spanish newspaper. Fast transcription with google translator (and some corrections) about the most important information:
"Everybody hold one´s cards close to the chest, that only serve to make enemies," he explained in conversation with this newspaper one of the members of the IOC, the Peruvian Ivan Dibos. In his view, each vote goes to "friends", which can harm the favorite in the first cut. "I have great fear of the second vote," added another IOC member, the Mexican Olegario Vazquez Rana, who believes that Tokyo will be the first to fall and Madrid's play against Istanbul.
Vazquez Rana is delighted with the work of lobbying by Don Felipe de Borbón. "I have doubts about the vote of at least three or four Latino members, but after having spoken to the Prince, I will back to Madrid," he explained yesterday, while Don Felipe chatted a few feet away with a prince of Malaysia, a member of the Jordanian royal family and a prominent Sikh Indian.
On the vote of the European countries is not so optimistic: "50% will back to Madrid. The others want to try it in 2024 or 2028, maybe Paris and the Spanish candidacy would prevent it ". Other sources, however, outlined the U.S. could unravel in a few days its aspiration to organize in Los Angeles or New York the 2024 Games, which inclined the European votes to Madrid by subtracting future options.
