There is so much that is so bad about Mexican and Dominican immigration that the case could have been made without referring to IQ.
IQ wasn't mentioned. I trust you don't fall into this category of those who crunch tacos and drink Corona and Tequila on this day.
That's exactly what happened, isn't it?
As far as I know - all the IQ statements reported by the MSM come from Richwine’s 2009 Ph.D dissertation at Harvard, which was read and approved by three tenured Harvard faculty members.
They do NOT come from the Heritage immigration study.
If I am mistaken - please - someone correct me.
