I have a feeling a couple of Governors are going to file papers just as this, their motives may be unclear but never the less I have a strong feeling that this issue will bear fruits if asked by certain people.
An example could be a cash strapped state that has suggested it will opt out of health care reforms, and the federal government is reticent to come to their aid, all that state needs is a certain action by a state representative asking for clarification of current eligibility status concerning the POTUS and the stroke of his pen.
In essence a state won’t broker a deal above or below board until it knows for sure the signing into laws by POTUS is in fact legal.
