Trump certainly did seem presidential at the AIPAC conference. That time, he had a prepared speech and it made quite a difference. The stream-of-consciousness off-the-cuff ramblings at his rallies are definitely entertaining but I prefer the AIPAC approach going forward. Even at the AIPAC speech, he was still able to ad-lib a little. But he stayed on track and delivered a great speech.
We need to see more of that!
