He did a very good job in the last debate because he fought tooth and nail with no holds barred, not because he held back and acted presidential like those losers Romney and McCain. If he listened to all the grow up and act presidential critics from the start, he would never have even become the nominee and the Clinton Machine would already have crushed him like a grape even if he had. We need an over-the-top fighter for a change.
Donald Trump has to focus on the things he can control, and the only fighting he should be doing involves the issues that people give a sh!t about ... not this stupid nonsense.
The only ones who give a sh!t about Hillary Clinton taking a drug test are people who support Trump anyway. He isn't going to win this election by shaping a message that appeals to THOSE voters.
