To be fair Trump can't string three words together without getting distracted either but he gets graded on his own curve, Democrats expect better from their candidates.
Actual Trump transcript from the other day during speech:
“I say, ‘What would happen if the boat sank from its weight and you’re in the boat and you have this tremendously powerful battery and the battery is now under water and there’s a shark that’s approximately 10 yards over there?’ By the way, a lot of shark attacks lately, you notice that? A lot of shark. I watched some guys justifying it today: ‘Well, they weren’t really that angry, they bit off the young lady’s leg because of the fact that they were, they were not hungry but they misunderstood who she was.’”
