Read "Art of the Deal-1987" available at amazon for $5 bucks. Trump has a history of being truthful {except when he was cheating on his wives}.
Trump can be truthful depending on what he said and when. He was a Hillary supporter and hoped that Obama was successful. Since I listened to Obama and knew his success was detrimental to our nation, I'm smarter than Trump. And if my name was on the ballot, I would not pick it.
