My perception of registered Republicans (not so much people who might incidentally vote Republican) is that the average age is pretty high. I wonder how these viewpoints sit with the older party members.
I suspect that the answer in this case is pretty simple. You have the interests of Republican voters (who, yes, do skew older) on one side of the issue, and the interests of Republican funders, who are generally big business types who are losing money every day their businesses are idle, on the other.
