If anything it should make him more popular here.
If this was published in some magazine 30 years ago I'm surprised the story hasn't surfaced more just in general since Arnold is a huge star. You'd think some Tabloid would have run a story on it years ago, and it would have been ingrained common knowledge for most people.
I find the radical latino group that Cruz Bustamante was in much more disturbing.
I can accept the fact of joining a radical group in the college. Its the past, so what. At the same time - this group sounds like the KKK. And you are definitely not going to see some Republican saying 'Yeah I was in the KKK, but that was 40 years ago.' Now a days that simply would not fly as an excuse.
