in part:
Trump's running mate, Indiana Governor Mike Pence, and Wisconsin Governor Scott Walker both gave very effective speeches, which will be drowned out by the story of the Trump-Cruz feud. It's hard to comprehend why Trump allowed Cruz to give a prime-time speech without securing a promise of at least a tepid endorsement.
Media reports are saying that Trump knew this was coming days in advance. Yet the campaign not only allowed the speech to go forward, but may even have actively whipped up the boos rather than encouraging followers to smile and pretend there was an endorsement somewhere in Cruz's tangled verbiage. If true, that means Trump's staff either somehow thought that this debacle would rebound to his benefit, or, even worse, that they were more intent upon punishing Cruz over a personal slight than presenting a positive and unified face to American voters.
For reporters, this has been the most exciting convention to cover in decades. For the rest of America, it's been a pretty sorry spectacle. Worse still, almost all of its errors have been unforced, the rookie mistakes of a campaign that is inexperienced and understaffed. Conventions are supposed to be coronations. What Trump has instead shown the country is a power vacuum at the center of his party -- one that threatens to consume his presidential hopes.

DO SOMETHING!
