You pretty much made the above extinct with the RINO pogrom. After decades of breeding with social conservatives and Christian fundamentalists, there are no pure blood strong conservative Republicans to be found.Too bad there isn't a strong conservative Republican running who has been principled and consistent for decades. If there was such a candidate, Republicans would flock to him in droves.
My link above your post is right from the Oct. 28, 1990 newspaper.
The timing is about right.
By the late 80s it became clear to many moderate Northeast republicans that the takeover of the GOP by the radical right and religious fundamentalists was inevitable they either had to get with the anti-abortion, anti-gay agenda or risk being branded a heretic.
