The name of the post sounded like the lead-n to a joke, but ... I feel ya. You have my sympathy, my prayers, and my two cents as well.

1. Realize that nobody embraces change unless they want to
2. Change your approach.
3. Lay off fo a bit.
4. Find an issue that resonates with her, and that she is likely to investigate on her own (child trafficking? monetary policy? investments? vaccines? school anti-drug programs that end up addicting more kids than no program at all?), and then get either entertaining references (movies, comics, cartoons) or solid verifiable evidence with an opposing narrative, which she can follow or not. Once one movie screen is torn, it's easier to accept that other parts of accepted reality are also different. Good luck!
   If those don't work, don't stress too much: she can wake up when everybody else does when the government takes over the channels and the confessions of HRC, Barack, etc., are all made public.
