Tour de France; What the f---k is going on?

I was loving the Tour. I was finally getting it, understanding the points, the jerseys, the tactics, etc. I was cheering for Alexandre Vinokourov, who had a horrible crash and some 30 plus stitches in his knees and kept at it. I loved that Michael Rasmussen, "the little chicken" was stepping up to defend the Yellow jersey when he would have been happy with the king of the mountains jersey and then....

First Vino, the day after he won his second stage with no chance of winning the tour, he gets busted.

And then days away from winning the tour, also after winning the stage for the day, still in his yellow jersey, little chicken gets booted by one of his teams sponsors.

They better change something and quick, because as much as I love the Tour, this is getting ridiculous.
