Just sayin’ though, sometimes we can’t see the forest for the trees.
Trump is learning that he needs to control his impetuousness.
He wouldn’t be the first prospective president to learn this.
George Washington did. History shows that the young Washington was concerned about his own hot temper, and he took great spiritual pains to cultivate patience. He was able to exercise great equanimity by the time he was actually asked to be president.
Repairing unfavorability is nearly impossible. The key element is with swaying undecided voters. Unfortunately for Trump, the number of undecideds is remarkably small. Sixty percent have already made up their minds that they do not like Trump. Compare that with only 37% for Cruz. Come November, who has a better chance at winning?
