She is gonna promise free stuff !
Probably, along the lines of the free college education thing, but I think Trump's promise of creating 25 million new jobs will also resonate with this crowd. Plus, people need to point out that when they talk about ‘free higher education’ they're talking about an even more hierarchical system, with the ‘free education’ coming from state schools and other public entities, while the Wellesley’s and Harvards, and Princetons, and Yales, etc. etc. will continue to be as expensive as ever. I fear that this would divide the system even further, unfairly (e.g. “Did you go to a ‘real’ university that you had to pay for, or did you go to a ‘free’ one?”).
