I saw her original post on National Review a few days ago. She's one of the first on her side to actually provide a statistics based rebuttal to Trump's statements. My impression is that she plays games with illegal versus legal immigrants. She also does stuff like compare crime statistics of immigrants not to the general non-immigrant population but to the non-immigrant population without high school diplomas. She does this in the article you've posted. It looks to me like she's got her finger on the scales all over the place and that there is ample room to rebut her.
Yes, after another poster pointed that out for me, I am now less concerned about her points, stats and articles. And now I have a basis to begin my rebuttal to the people I have to rebut to this weekend.
I knew there had to be something wrong, thank you all Freepers for helping me out here.
