Trump can instantly craft the tiniest zinger, turn the smallest pebble into a emotional bunker-buster. He told Rand "you're having a bad night". On Perry it was "he wears glasses to seem smart". Bush of course was "low energy" and the next day Bush responds by literally jumping in the air to show his virility and enthusiasm. All he did with Bobby Jindal was to refer to him as a "lightweight".
Trump simply flicks his finger and they all simply fall apart in front of our eyes revealing their true measure.
Yes, think Jindal. Wow, I haven’t seen this from anyone but Rick Perry. Oh, wait? Rick is out of the race and Jindal is at 1%.
