The Democratic National Convention is due to open tonight (Monday), but with Barrack Obama already established as the party's presidential nominee and Joe Biden it's vice-presidential, some writers were asking whether the convention -- as well as the upcoming Republican one -- doesn't merely amount to a political infomercial. Others were questioning the need for a political convention at all. Drama was building over whether ailing Massachusetts Senator Edward Kennedy would attend tonight's (Monday) session. The Boston Herald quoted his son Patrick as saying that his father wants to attend a planned tribute that is to be staged for him tonight. Meanwhile, ABC News is using the convention to launch the expansion of its news programming into HDTV. Not only will it carry the conventions in HDTV, but also its World News With Charles Gibson, Nightline, Primetime and 20/20.
