The first Obama-McCain debate is on Friday, 9.26, at 9 pm eastern — eight days hence. A foreign policy focus, I’m hearing, because the Obama team didn’t want to get into domestic-cultural stuff at a debate held in Mississippi. Twitter.com and current.com are trying to get everyone to post twitters during the debate. Current is promising to “broadcast as many of your debate tweets as possible right over Obama & McCain, in real time, on our live broadcast.”
