I honestly think he did :S
He didn't though. The fact is that both you and a few others keep saying that and the main argument is which one of them is more lucid
tells you how pointless and non decisive these have become. Trump staying on point and not going of script is the least you would expect from any candidate. Why he gets lauded for it.
Four people from four parts of the US have explained to you how he has done himself no harm including someone who lives in Texas pretty much debunk your comment about the oil comments.
Winning a debate tonight means nothing. The very fact people look to see who wins says it all.
Again most people know who there voting for and this will have done nothing to sway that.
Given most of the points had nothing to do with issues in swing states there is nothing for them to talk about and decide.
Thats simply what it is about. Many states have had a massive jump in early voters already long before tonight.
Trump needs key demographics none of which he has done anything tonight to sway.
