I don't get why he'd fly for 40 hours. You can get to Auckland from London in less than 30. From Rio, where Greenwald lives, my googling suggests he should be able to do it in well under 20 hours.
Unless he's counting the time he expects to spend flying back.
But "what did he think he was doing" - I imagine he's doing something he believes in (telling what he knows, or thinks he knows), and Kim Dotcom is paying his expenses to do it. That looks to me like the Path of Least Tinfoil to an explanation.
As for the Internet Mana party tanking - well, it started from basically nothing, so it's hard to say it's gone far downhill. What the whole episode tells us is that Dotcom, for all his genius for publicity, doesn't really know much about politics. Yet. He's practising, and I'm sure he'll learn.
Personally, I think both Dotcom and Colin Craig are deliberately trolling us. They're too entertaining to be genuine.
