Progressives, whether Democrat or Republican, always challenge the truth by attacking the messenger. It's a time-honored tradition with them; unfortunately, it works way too often. And of course, politicians like Rubio and the other 7 have a big political stake in what I like to call Illegal Immigrant-Care so they have to jump on the band-wagon playing the same song. What really bothers me is that a politician, any politician, calling a validated, honest researcher a racist or saying the researcher's study is flawed is comparable to a second-grader calling The Big Bank Theory poorly applied science. Let Richwines' peers do the review not some self-annoited politician that has neither the education or the integrity to make any comment value.
