Marco Rubio used no teleprompter, didn't flub his words..his voice and cadence was clear and forceful, soft when it should have been. He was standing under hot lights, with no podium to hold a glass or carafe of water. And yes, his mouth was dry, he had to wipe perspiration from his brow, and then there was a awkward attempt to give him water by thrusting a water bottle at him. Rubio never missed a beat and grabbed the water bottle and took a drink. obozo would have lost his place on the teleprompter, he would have stumbled and flubbed his words and the speech, he would have made excuses for why he flubbed, and in general have made a foool out of himself.
You did good, Marco.
