Although he may have been required to register, how would his failure to register preclude him from being president? (Is there a penalty such as barring him from all federal jobs?)
From the Selective Service website: "Employment in the Executive branch (and Post Office) is barred to any male who did not register between the ages of 18 - 25. "
Yes, there is wording in the law that failure to properly register makes one ineligible for federal employment. I don't know if that applies to elected officials.
Yes, the penalty for not registering is that the person can not hold a position in the executive branch of the government. I heard it said he registered late at a P O in Hawaii, but at that time he was in the US at school... so someone else, reportedly an uncle or grandfather is said to have submitted the registration. I believe there has to be a signature on that document and I’m sure if anyone cared that this fraud is not going to abide by the very constitution he is going to swear to uphold they could verify who actually signed the document... my guess — It twern’t Barry!
