Senator Coburn and many others, Bill O'Reilly for example, are confused with the difference of "impossible" and "difficult" or even "unlikely." It wasn't impossible. It was only made more difficult by people like Coburn and O'Reilly who wouldn't make the effort. In any event, George Washington took Jamestown even though others thought it was "impossible." But it was just difficult.
Yes, I guess you are a RINO, Senator Coburn.
