CLEVELAND — Donald Trump did not get what he needed from the first day of his convention. He has three more tries.
Trailing presidential candidates need their nominating conventions to delivering broadly appealing messages with a minimum of static interference. This one opened with lots of static.
The first bit of interference came from Trump's own campaign chairman. In a breakfast with reporters, Paul Manafort accused Ohio Gov. John Kasich, who has declined to endorse Trump or attend the convention, of "embarrassing" his state.
That note of unprompted discord was followed by a boisterous protest on the convention floor. Anti-Trump forces, having failed to "unbind" delegates in a long-shot bid to dislodge the nomination from the New York billionaire's hands, sought a roll-call vote on convention rules to register their displeasure.
When the Trump campaign and Republican National Committee steamrolled their plan, the dissenters unleashed a torrent of boos that undermined the candidate's attempt to demonstrate party unity.
Convention planners had more control over the evening program, the theme of which was to "Make America Safe Again." A series of speakers ripped President Barack Obama and Hillary Clinton for weakness at home and abroad — including the mother of a Benghazi victim who said she blamed Clinton personally for her son's death.
