The folks over at Bluegrass Bulletin has this to say:
Grayson is reported to have called Rand Paul "an outsider" and then followed that up with words some are suggesting amounted to an accusation that Dr. Paul is a non resident.Now this is a pretty bizarre way to attack an opponent. Most voters I think care about the integrity of the candidate and the ideals they believe in. Not, some arbitrary length of time a candidate has lived in a particular geographical area.
Rand Paul is an eye surgeon who practices medicine in Bowling Green Kentucky where he has been raising his family for 18 years.
Another thing to point out is that Grayson used to be a Democrat. While Grayson was campaigning for Bill Clinton, Rand was a solid Republican fighting for lower taxes with his Kentucky Taxpayer Group. I could be wrong, but I think Republicans probably care more about a person's Republican bona fides then they do about how many decades a person has lived in Kentucky. I don't have exact facts, I think it's possible Rand Paul's been a Republican longer then Grayson has.
