As annoyed as I am about Bono these days, I have to admire the guy for trying. You gotta try to change things. I think Bono's influence on the disgusting Bush administration has allowed one of the few decent things Bush has done -- aid for Africa; the other might be allowing illegal immigrants to become legalized. (I'm not saying it's a simple issue, but it's amazing that Republicans won't tolerate Mexicans but will accept Sarah Palin potentially being the next President.)
Anyway, I, too, found the guy both gutsy in facing down Bono and arrogant; it's like he has more respect for Axl Rose not giving a damn about anyone than Bono's efforts. I'm very proud of Bono's DATA work. I also find it hilarious that the guy is trying to full take credit for the debate as standing up for the little guy (sorta like Bono trying to represent African interests, no?) when Bono suggested it.
It's good to give celebrities hard questions, though. It doesn't happen enough. De Rogatis caved when he interviewed Bono in response to his scathing review of HTDAAB.
How much this guy is inflating his interaction with Bono aside, the issue of celebrity politics is an interesting one and one that works sometimes better than others. I think for short term, one-off campaigns (ending apartheid, for example) it works better than prolonged campaigns, but I've done no real research on the subject and I doubt anyone else on this thread has either.
I have very mixed feelings about Bono's work - coming from an economic development background, I disagree with Jeff Sachs, his main advisor. I think Sachs (and Bono of course) are well intentioned, which is all well and good, but may be unintentionally causing harm by advocating the wrong approach. I'm not certain on this, because I'm not certain (and no one is) what the right approach is. But Sachs is a pop economist who doesn't have enough depth to be right. I worry, as others have mentioned re: Red, that doing the wrong thing or something comepletely ineffective will prevent people from doing something that's actually good, even if it doesn't cause direct harm.
On the other hand, I'm incredibly proud that he cares about these issues enough to try and do something about them, and I admire his passion (even if I wish he'd finish the damn album and play some more varied setlists instead of ones that lead into the same old speach).
As for the Bush thing, I don't think that without Bono Bush would have given no aid to Africa. Bono certainly encouraged Bush, but Bush's evangelical outlook means that he probably would have done this anyway. And a president who wasn't Bush (Gore, Kerry, whoever) would surely have given as much or more aid to Africa without stupid pro-life, anti-birth control strings attached, and without Iraq competing for funding.
