The testing in place when Donald J Trump was admitted to the Warton School of Business was such that those who were accepted had very high IQs. I have read that Trump’s IQ is about 158 Stanford Binet. That puts him at the middle of the upper one percent. In other words Trump has an IQ higher than 99.5% of the world. So, yes he will know how to campaign to win. He has a keen intellect and even sharper level of street smarts.
Then he needs to get on it. My oldest who follows politics more than me says he’s not giving Americans a reason to vote for him.
