The union line is, what jobs are not sold overseas, are being taken by illegals. I personally don't believe that, a vast majority of unionites do.
My sources are this: my brother is UAW in Bay City, Mi, my sister is pres of her local in Flint, Mi, I am a member ofUAW 113 in Muskegon, Mi.
I believe most members in Mi are of this mindset.
