It's the manufactured issue used to limit time spent talking about the speech.
The word "shakeup" originated with the WSJ reporter who "broke the story." She talked to Trump yesterday, before the speech, and asked if it was true that there was going to be a campaign shakeup. He confirmed the new hire and promotion. The reporter, on CNN, was aksed if Trump used the word "shakeup." The reported said, no, that was her choice of word.
LOL - Live on CNN, trying to intro the Green Party townhall, couple of hecklers behind the reporter, one with Trump bumper stickers.
Trump surrogate comes back with "See polls relating to Brexit." And "There is a movement that the polls are not showing."
No rebuttal from the #NeverTrumpers. Let's move on ....
