Harry Reid is truly Mormon, a very devout and devoted Mormon, a part of the elite who qualify to enter the Temples and participate in the secret ceremonies.
Harry Reid has to renew his ID every year and be vetted every two years to be at his highest level of Mormon status, he is among the elite in faith and devotion.
Post 80 also applies to Glenn Beck and Mitt Romney, they are all three, “Temple Mormons” and are allowed into the Holy temples for services and marriages, etc, and the secret ceremonies, all of which are forbidden to the average Mormon, who are forbidden to even enter those temples.
That is why the ID is issued and must be reissued annually.
