And if you have zero chance with those voters anyway, what is the harm? That they will tell other people that you are a terrible "poyson"? They were going to do that anyway. Come on, give me another reason to be a hypocrite and waste my time being nice to people who despise me down to the ground.
This issue of control and political donations goes back at least to Harry Truman's 1948 campaign. What Trump accuses contemporary Jewish donors of doing, viz. donating to control, is the complaint that one of the Truman women (Harry never said it publicly that I know of) made about that campaign, that three AJC guys came to Harry and said, "do this or else our money all goes to Tom Dewey". "This" was to recognize the Israeli government proclaimed by David Ben Gurion, something the white-shoe antisemites in the State Department were telling Truman not to do.
A History of Zionism treats the meeting between AJC and Truman differently while acknowledging that it took place. In the HoZ recounting, the AJC men simply came to the White House in hopes of meeting Truman and persuading him to recognize the Israeli state. If only they could see him for a few minutes, the historian tells us, they felt sure they could persuade HST to "do the right thing".
If trump believes he has zero chance with the group he was addressing, why was he there?
