VDH is sorta right here.
Newt just needs to stick to issues and inspiration. It’s what he’s good at. When you explain why you lost, even if what you’re saying is technically correct, it just comes across as whining, and makes people focus on the loss, instead of preparing for future victories.
Also, when you lay out detailed reasons why you lost, and try to demonstrate particulars in your argument, the simple fact of the matter is, a lot of people are simply not intelligent enough to follow the argument. To a stupid person, a complex argument is easily confused for making excuses or trying to obfuscate an issue.
Probably a good thing to do would be to reframe the contest so as not to focus on a loss, but rather to have people see each state contest more like one inning in a baseball game.
