I think it will be fairly close.  I see a 52% - 47% Clinton win with 1% to the widely popular "Other".  I'll also predict about a 35% turnout or roughly 1.4 million votes.  That would give Clinton about a 70,000 vote popular vote advantage (730,000 to 660,000).  Due to the close popular vote, the delegate spreads in some of Clinton's strongholds will break 3-2 for her instead of 4-1 which will lead to a +7 in delegates (84 - 77).
