At the 1:24 mark, Dennis Goldford of Drake University says it in the AP report below.
I was enraged that Sarah Palin endorsed Donald Trump ahead of the primaries. But there was one paragraph in her speech that really expressed Trump’s appeal. It is a little bit choppy but it is mostly understandable:
Trump’s candidacy, it has exposed not just that tragic ramifications of that betrayal of the transformation of our country, but too, he has exposed the complicity on both sides of the aisle that has enabled it, okay? Well, Trump, what he’s been able to do, which is really ticking people off, which I’m glad about, he’s going rogue left and right, man, that’s why he’s doing so well. He’s been able to tear the veil off this idea of the system. The way that the system really works, and please hear me on this, I want you guys to understand more and more how the system, the establishment, works, and has gotten us into the troubles that we are in in America. The permanent political class has been doing the bidding of their campaign donor class, and that’s why you see that the borders are kept open. For them, for their cheap labor that they want to come in. That’s why they’ve been bloating budgets. It’s for crony capitalists to be able suck off of them. It’s why we see these lousy trade deals that gut our industry for special interests elsewhere. We need someone new, who has the power, and is in the position to bust up that establishment to make things great again. It’s part of the problem.
I think this corresponds rather well to the “middle finger segment.” It also show why attack ads don’t work against Trump. Donald Trump represents American anger at our ruling class.
