Reid is a fellow Mormon—I don’t know why the church hasn’t sent him packing.
In a ‘poetic justice’ sort of way - Reid’s maniacal attacks help demonstrate - there are Mormons and then there are Mormons; much like the rest of society. They are not monolithic, marching in lock-step.
So we can deduce that Mitt Romney is a quiet Mormon and Reid is a Moron Morman.
