 So I'm, for the most part, taking their campaign at their word that he had a cold. He probably did. The fact that he had a cold does not in any way explain the fact that he couldn't talk. Again, even if you want to say that that explains his hoarseness, it probably would. And again, he may have had a cold. It may have also just been all the prep work he did. If you spend a week and a half doing mock debates and so on and so forth, it may have taxed his voice.
