I also don't get her constant repeating of having "raised" 23 foster kids when in truth they rarely stayed with her more than a month or two. If that is a qualification for president, then my cat "Peaches", who mothered two litters of kittens before she got fixed might make a good congressman from northern california.
Fostering children can be a noble thing, depending upon motivations and circumstances, as some do it for financial purposes for the extra income and are not particularly good "parents", as talking with anyone who has been through the foster care system as a kid could probably tell you. Just doing it doesn't mean ALL that much, and i would check her kids for having had microchips implanted.
If she wants to hang her hat heavy on that, be prepared for all 28 kids to be featured, reality showed, and dancing within a few months.
