Conversation topic of the day: has anything changed since Ohio and Texas? Is anything at all more clear because of yesterday's vote in Pennsylvania? Despite winning yesterday, Clinton's chances of winning the nomination have steadily declined, as the margins between her and Obama have held constant, and the pool of available super- and pledged delegates has shrunk considerably. The arguments about arguments about the superdelegates, fundraising, etc. will inevitably continue, but has anything really changed in the past month and a half? I open it to you, dear readers.
