The primary has dragged on for so long now that supporters in both camps have a huge emotional investment in their candidate, and more importantly, a great deal of animus for his/her opponent.

The winner will have to really talk up the loser and emphasize the common goals of both candidates.
However, that simply won't be enough for some people. Instead of really contemplating the chilling prospect of a McCain administration, they'll continue to hold a grudge and sit out the GE.
