This is what passes for news these days

So John Edwards endorses Barack Obama. In other news, water still wet. I mean, why is this worth a big ol' headline? I loved John Edwards as a presidential candidate, but this looks pretty craven, especially since it appeared that his position on universal health care was closer to Hillary's, and that Obama blew it in their initial talks about an endorsement by being glib, aloof, and dismissive. He seems to be coming in at the last minute, when it's obvious that Obama can win-has won!- the nomination without him. What gives?
