Obama converts 2 more Edwards delegates from Iowa and picks up one more superdelegate from Wisconsin. Obama's lead slowly but surely grows during this time between primaries. A number of people have noted that there have been *NO* new superdelegates added to the Clinton column since Super Tuesday, while Obama has added a bunch. Has she just been telling all of her supporters not to announce so she can have a big announcement one day with a whole bunch of super delegates? Or is she actually not convincing any more of them? Dunno.
Anyway... if Obama keeps getting delegates here and there in the time before Pennsylvania, it will raise the possibility that even when Clinton wins Pennsylvania, will she actually end up in a better position than she was right after Ohio and Texas? Or will Obama have gained enough ground by then that she closes the gap, but only to mid-March levels? It depends how many more superdelegates Obama is able to round up in the meantime, and if Clinton starts grabbing some of her own too.
