What did you say to convince her/put her over the edge?
There wasn't any one thing in particular, but if anything seemed to resonate most, it was that I hammered how little Trump understands about foreign policy and he'd have nuclear warheads at his disposal. Follow that up with Trump's taxes and the NYT revelation Sat night.
Make this simple. College educated white voter in her 50s from an affluent household in vegas suburbs. She believes Obama hasn't been very good for the economy but she doesn't dislike him or think of him in a negative way. The general feel I get is that she thinks the economy and other things should have gotten a lot better by now but that it hasn't, and Obama is President so it falls on him.
I didn't spend any time trying to defend Obama, I figured it wouldn't do anything.
This voter expressed heavy concerns about Trump. She initially supported because Trump is such a good businessman and not like other politicians. But as time has gone on, she has been appalled by the things he's been saying, specifically in terms of women and minorities. In additions, she expected actual plans for the economy and things like terrorism already.
As much as I'd like to take credit, I think debate really swung her vote. She said he clearly lost, he ignored questions and gave no plans (even mentioned about police race relations as a non-answer which she thought was absurd), acted disgusting. For Hillary, she doesn't like Hillary...but she said Hillary looked good up there, Presidential.
All I did was hammer home that Trump has no actual plans (besides build a wall). I explained how incompetent he is and how nonsensical his few ideas have been. Then I just brought up the nuclear stuff and foreign policy stuff which she said scared her a lot. I discussed the new tax story (which she also found appalling) and I told her about Trump's charity bullshit versus Hillary's (I countered her claim with "but I heard she got money from Saudi Arabia for access with the fact that there is no evidence, her charity is higher rated than the red cross, and all that money went to pay for AIDS medication).
Anyway she told me "every day I see myself more and more voting for Hillary." She told me I really helped her and that she didn't think she could see herself actually voting for Trump, anymore.
She's the target demographic of the Clinton campaign. I'm just doing the Queen's work.
edit: Also, her kids are very anti-trump and have been in her ear (millenials!)
