I do not agree with you. The exclusion of Astana was not arbitrary. It occurred because of positive drug tests by members of that squad. The ASO was struggling to maintain the image of the Tour and had to make sure that teams that rode the Tour were clean. The organization is not banning all non-French teams to ensure a French winner. It excluded one non-French team that had a problem. It is too bad that Contador and Leipheimer were excluded (although Contador was not fully investigated in Operation Puerto), but under the circumstances, the ASO did the right thing.
Actually no one on the current Astansa team has ever been involved in a verified doping scandal. If ASO used the same criteria - the sponsor name had been involved in doping in the past - then none of the of the teams should be competing in the tour. Basically the tour is turning into a joke where ASO is beholden to no authority with cycling jurisdiction.
I see your point, but I have three counters. First, your initial post expressed the view that the ASO was trying to boot Astana to eliminate non-French competition. We both know that all of the non-French teams would have had to be excluded because the French have no one who is currently capable of winning the Tour. Second--again, Alberto Contador was not fully investigated. Not all of the blood bags were tested, and the initials A.C. were found on one of them, but the investigation went no further. The Spanish satisfied themselves with people, primarily foreigners, whom they could catch easily such as Jan Ullrich, Tyler Hamilton, Ivan Basso, and Francisco Mancebo. Third, the ASO is a private commercial organization that sponsors races. A number of them exist in Europe. I see nothing wrong with that. Some of them have shown more firmness in dealing with doping than the UCI. It is good that there is diversity. Perhaps it is time for racers to turn their backs on the UCI.
With the arbitrary decision to ban Bruyneel and the Astansa team along with some of the leading riders in the sport, the Tour de France has become irrelevant. The tour owners have lost the American audience and many others internationally. From now on the real events to follow are the classics. Eventually ASO will ban all riders until only French riders are left competing so they can say they have a French champion. The French are great people but ASO is joke as a profession sports organization and reflects badly on their fine country.
