In my comments I have always said that Lula is a loose cannon, but apparently, so is Daley. Not to mention the Madrid guy. He came out with "I will always emphasize the weak points from my opponents" after the Madrid committee issued a formal apology. Those guys are going to make clumsy statements.
Fortunately, on the Rio side, the worst we had so far in Denmark was Pele mistaking Michael Jordan name for Michael Jackson. Lula started pretty good.
Daley can keep it under control pretty well, though - especially when discussing plans and when it's a project that matters to him. When he doesn't give a straightforward answer to the Chicago press, they'll be asking him the same question for the next month and bringing it up every chance they get - so, my thinking is he just figured that an obvious, self-evident answer (the World Cut is all soccer; the Olympic Games are different) to local press outside City Hall couldn't possibly be controversial. I'm certain Pat Ryan and the USOC's briefed him throughout the whole plane ride about what needs to happen over the next few days.
