I'm not sure that requesting Michael to step into another family feud would be the right response to counter his brother.
I'm beginning to wonder if there hasn't been a massive screwup of teh paperwork concerning the Reagan children. I believe Michael is the biological child of Ronand Reagan and the other children are adopted !! (Or found under some rock !!)
I agree that Michael needs to be left standing in this thing for the sake of the father only he ably represents.
Nancy does not need another reason to alienate him and his children. The woman may be a shrew but Michael is most likely to honor her for the sake of his father and his belief system.
What is fascinating is the difference between the two children raised by Jane Wyman and the two raised by Nancy Davis. To me it defies comprehension in particular because Wyman was a liberal.
