You assume that the posture taken by every candidate during their campaign is the one they maintain once in office.  Clearly this is not the case, and ex-members like Beth Fukumoto clearly had the destruction of the party in mind.  Still others, like Lauren Matsumoto, who still officially maintain party membership, claim to have no party affiliation and would rather "have their name" on their house seat.  And you want the party to mentor these imposters?  Their constituencies feel used and betrayed and absolutely do not condone wasting party resources on them only to be abandoned when the time is convenient.
