This is the one that I have knowledge of that I wouldn't have minded failing to be confirmed. The red flag to me was her answer on standards, and that she wouldn't commit to demanding the same minimum standards for private schools receiving federal funds. Now, there are legitimate reasons one could contest federal standards, but I'm not sure I believe that those are her reasons. I would have rather seen a different candidate.
+ allowing more parental choice for schools
+ + due process rights
+ supporting individual school districts decisions on whether to allow armed staff or not
- - standards
I hope she works out, but I wouldn't be surprised if she is a huge mixed bag.
