Heath Haussamen has a post
today that the reason Senator Domenici is resigning is because he has frontotemporal lobar degeneration
, a degenerative brain disease. It may incapacitate him, it may not. It may take years, it may not.
I think it's clear that something
has been affecting him in recent years. I hope he is able to complete his term without further ill effects, and that he is able to enjoy at least some years of his retirement.
It's horrible the way our bodies can sometimes outlast our minds.
