There are several people still living who were there who say it wasn't a smear (hence the name, Swift Boat Veterans for Truth).
Sadly, it has now become a "smear" to merely point out what a left-wing candidate has said or done.
Now, as to conservative/Republican candidates...see Dan Rather and his Texas National Guard documents.
That's my point. I believe the Swifties who were there and I contributed to their effort to unmask Kerry. He's been living an offensive lie since the Sixties.
