Too many cooks spoil the broth. Let Trump negotiate it and have all the others tag along, as they have been doing the whole campaign.
That was sort of my contention when I read that something like 11 managers from the various campaigns met ... and I thought 'why didn't the candidates themselves meet and cut out all the middle men?'
Trump probably knows more about the inside workings of networks than any of the other candidates or their managers. Trump has had business with the networks many years.
