According to the tracker, Obama needs just 288 more delegates to secure the nomination. That works out to 40% of the uncommitted delegates. Also, given that he's a lock to get at least 200 more pledged delegates, it means he really only needs 88 of the undeclared superdelegates -- just under 30%.
Bottom-line is that barring a catastrophic collapse, Barack Obama's delegate math is just unbeatable. Of course, the media doesn't want to tell you that story -- if people stopped paying attention to the primary campaign, their ratings would suffer.
As for me, all I know is that I barely watch news on television any more -- I just DVR the evening broadcasts and sometimes check them out. (And until the mainstream news blogs start covering the general, I won't be spending much time on them either.) I still do watch is Countdown, though.
