Politicians often ask questions they already know the answers to. They are not on "fact finding missions"; they are trying to score political points. That's why Markey's letter was public.
Iger's hostile response suggests he forget one of the basic rules of politics. Iger's response might very well help Markey score political points.
The characterization of Iger's response as "hostile" is subjective, even so, if Markey was acting loopy by not researching stuff, Iger could be legitimately peaved that Markey didn't do his due diligence. I think Iger swatted him down like a bug, and made him look like an amateur.
Foaming at the mouth may have worked well for Barney Frank, but it doesn't play well in Peoria. People out of Mass probably wonder if Markey has rabies or something . . . you get the picture. Anger over loose gun control is important, anger against the beloved Mickey Mouse and Disney over what looks like is a good idea and the future . . . poor move Markey.
As I posted earlier on this thread, with Scott Brown out of the race, I still think Markey does nothing with it until he's in the Senate. Once he's in the Democratic controlled Senate, he can use Iger's letter as an excuse to score some more political points. Until then, he's the frontrunner and the Senate election is his to lose. He does not want to rock the boat at this time.
If Markey scored political points against Iger in a clear manner, don't see why he couldn't trot that out as something noncontroversial to talk about during the election.
I've been watching Washington Week, reading Time, since the early 1990s, and read politics all the time on the web. I don't at all see your angle with regards to using Iger's letter. Like an imbecile, he could dance around the well of the Senate and yell about Mr. Iger being mean to him . . . nobody cares, actually, Disney has deep pockets and donates to campaigns, and some famous politicians have been on Disney's board.
I'm not trying to defend Markey, only trying to explain what I think might be happening and how it might impact Disney. Since this forum is about Disney and this thread is about "opinions", I think at least some people might be interested in reading what this exchange of letters might mean.
You believe that Markey is waiting to launch an attack on Disney when he gets into the Senate. Even if he wanted to, can he convince enough Senators to do this? Very, very doubtful. What would the bill be? The "Let's Attack the Blatantly Evil Next Gen of Disney Bill!"
There's also the House. I suppose for some reason he'll be able to get the votes needed there?
Markey . . . doesn't matter in a way that could harm Disney, Iger knows it, and called him on it, and for wading into an issue he doesn't understand.
