I had to go with 'not sure' simply because who knows about those that were let in during our dictator's rein.  Our borders were 'open to the public' as long as 'you' voted for 'me' attitude.  Also, don't forget about the hidden cells that pop up every now and then, they are not necessarily muslims either.  We are really not 'safe' until the Libs stop 'looking for votes'.  One sure way to stop the libs, take away his mighty pension and put them under Obamacare.  LOL, watch them squeal like a pig!!!!
