I have to ask: what does your post have to do with the article in question?
This is an article about a GOP congressman who openly endorsed Trump early on, who stood up to the left wing astroturf and who was rewarded for it.
Answer: From what I have read, most GOP reps are facing astroturf rabble-rousing crowds sent in to dispirit them. So the “story” is that at their town halls, they face screaming crowds of protestors. While that may be a true accounting of the facts, IOW, accurate reporting by someone who might be on the scene as it happened, the protestors are not folks who would contribute to his campaign and never supported him in the first place. What little footage I have seen is of protestors who were screaming like stuck pigs because the rep advocated taking away their beloved 0bamacare; an illustration that this was not a GOP crowd, at least measured by scream volume.
