While Madelyn Dunham and her husband from what I have read had strong communist leanings which I do have issue with, I also would not fault them for trying to ensure security for their grandchild. I would do the same. My response was regarding others saying how would she have know he might be President...she didn’t. She just certainly knew that in 1961 it would be better for him to be legitimate and entitled to American services— he said his mother got food stamps. Those services would have been easy if he were American.
The issue of legitimacy would be important because I question how Obama’s mother could ever have been legally married to Obama Sr. since he was still married to his wife in Kenya with whom he had 2 more children after BHO.
