Here's the speech from 2007 that broke today in which, among other things, Obama gives a shout-out to his pastor, the Rev. Jeremiah Wright.
The accent is...bizarre. It's like he borrowed Jesse Jackson's vocal chords for the evening.
Mostly it just seems like typical boilerplate delivered to an important segment of his base. I admit that I just skimmed through the video, but the part I did see and hear was kinda...meh. I mean, there's a lot of garden-variety liberal crap, tailored for a black audience, but nothing new (unless I missed something).
And there is the bogus accent (or is the one we're now familiar with the bogus one?)
