Somehow this argument does not sound convincing. Yes, one shouldn't expect too much from a mere petition - but that's what was said from the very beginning!
As for president's apparent inability to change laws - give me a break. He's the leader of the major US party who just won the elections, he controls the Senate, he has wide range of supporters in the press, he can successfully solicit billions in donations - and he's absolutely powerless to do any effort towards fixing this little thing? Somehow I have hard time believing it.
