The ONE Campaign’s put together a useful website, on the record that lets you see what the various presidential candidates have committed to in terms of extreme global poverty and disease. It’s got a comparison feature which reveals that the three major Democrats all have pretty similar positions. And sound ones at that, which is very good news, though with something like promises to spend billions on improving developing world access to education, the crux of the matter is not so much the difference between Clinton and Obama promising $2 billion a year and Edwards promising $3 billion a year as it is the question of what congress is willing to pony up.
On the Republican side you see some bigger difference. Here’s Romney, Huckabee, and Giuliani, for example, where you’ll see that Huckabee’s committed to doing the most whereas Giuliani’s never so much as publicly addressed most of these issues. That should tell you a thing or two about hizzoner’s depth of understanding of world affairs — he hasn’t rejected a particular approach to global poverty and development issue, he just hasn’t devoted any thought or attention to the issue whatsoever since if it doesn’t involve killing people or grandstanding, I guess he’s not interested.
