Republicans are bracing for the possibility of a drawn-out fight over Donald J. Trump’s nomination that could stretch into the convention next week, a spectacle party leaders are desperate to avoid.
As the party’s governing body convened in Cleveland on Wednesday for a series of organizational meetings, the possibility that the smoldering dissent over Mr. Trump could become a full-blown eruption on the convention floor was a top concern.
Party officials were working in overdrive behind the scenes to beat back two challenges. One would force a vote that could theoretically open up the convention to any candidate who wants to seek the nomination. A second, organized by supporters of gay rights, would strike the entire Republican platform, which is staunchly conservative in its treatment of sexuality, gender and religion.
