The organisers of the Tour de France have been informed by Marc Biver, the manager of the Astana team, about the positive test of Alexandre Vinokourov on the day of the time trial stage in Albi. At the request of Patrice Clerc, President of A.S.O., the Astana team has agreed to leave the 2007 Tour de France.
Bicycling.com had a little more analysis:
So much for dreams of a clean sport. After winning two spectacular stages, Kazakhstan's Alexander Vinokourov tested positive for blood transfusion today.

[Tour Director] Prudhomme was even more emotional. "This is proof that the actual system doesn't work. And we don't want this system any more."
In a blanket statement that seemed to target the ability of the International Cycling Union to govern the sport he continued, "A system that doesn't defend the world's greatest cycling race, doesn't work. The future of cycling is through the Tour de France. What other event can bring together so many fans? But the system doesn't work any more. Reform of the system is impossible...only revolution will change the system. We must explode the system."
The "system." The "system" is a fucking joke. We have no final decision yet on Landis, even, and that was the 2006 Tour! Nothing's working, people are still doping, and the testers and their gestapo techniques aren't catching people. Not to mention the lab is leaking results to newpapers before actually telling the competitors! Yeah, we need to reform the "system." I love cycling. I love to do it, I love to watch it on TV, I love the strategy of the stage races, and I get goosebumps whenever I see footage of the peloton streaking along the countryside. And I'm really sad to say that the sport is going to slowly wither away and die if the whole culture doesn't change. It's no longer a matter of more inspections, or more testing, or more penalties. What we have to do now is change the culture, make it not "normal" to dope, make it not something "everyone does."
I hope Vino loves his sport enough to be honest, cop to his offense, and help root out the problem. I don't want to listen to him deny and deny and listen to the lab claim and claim and listen to his science experts say "oh the lab did it all wrong" and have another fucking YEAR of arbitration! Everyone's sick of this. Nobody's going to care soon. Cycling will steadily lose fans and supporters and advertisers. And a sport with no fans is dead.

Boulder Report blog by Joe Lindsey:
ETA this quote: The Tour de France is breaking down as well – a great event brought to its knees by people who are so beyond selfish, so willfully arrogant that they would risk the destruction of the most beautiful sport in the world for their own vain glory. It is absolutely toxic to the sport – it’s impossible for fans to cheer on riders while simultaneously wondering which of them will test positive and get kicked out for cheating.
Emphasis mine. That sums it up perfectly.
