I'm hesitant to even give him 1/10 stars because that would imply that I at the very least consider him a politician. Donald Trump saying he's a politician is the billionaire-equivalent of a waitress saying she's an actor.
Donald John Trump, Sr. (born June 14, 1946) is the 45th and current President of the United States, a businessman, author, and previously a television personality.
Born and raised in Queens, New York City, Trump received an economics degree from the Wharton School of the University of Pennsylvania in 1968. In 1971, he took charge of his family's real estate and construction firm, Elizabeth Trump & Son, which was later renamed The Trump Organization. During his business career, Trump has built, renovated, and managed numerous office towers, hotels, casinos, and golf courses. He owned the Miss USA and Miss Universe pageants from 1996 to 2015, and has lent the use of his name in the branding of various products. From 2004 to 2015, he hosted The Apprentice and The Celebrity Apprentice, reality television shows on NBC.
On January 20, 2017 he began his service as the 45th President of the United States. More: en.wikipedia.org.
The question (in this case) isn't how likeable he (or any politician) is or how (high) you would rate his political agenda, but how well his rhetorics support his views. Does he have a (realistic/(long-term)benefactory) vision? Does he have integrity or might he fall into (i.e. economic) corruption? Do you expect him to able to survive the political arena (for multiple years)? Is he experienced, well-connected? If not, do you expect him to be able to live up to former politicians you have a high opinion of?
Trump is a strong personality and someone America needs to be great again. He has his antics, but he's a good man inside. I don't agree with all his views, but I think he would be great for our economy.
