It's a common practice for campaigns to send out trackers to follow their opponent's every move. Trackers videotape candidates' speeches and interaction with voters.
The high-minded objective of a tracker is to get a candidate on the record so he or she can be held accountable for what is said.
But mostly, trackers want to catch the candidate doing or saying something stupid or embarrassing.
Campaign strategists warn candidates about trackers and tell them never to engage them.
State Attorney General Darrell McGraw didn't get the memo.
Campaigning with several other Democrats at the Pumpkin Parade in Milton, McGraw had a confrontation with Justin Lafferty, a 24-year-old campaign staffer for McGraw's challenger, Republican Patrick Morrisey.
Lafferty was taping McGraw with a flip cam while he was having an informal debate with a woman identified as a Republican candidate for the House of Delegates.
McGraw approached Lafferty, asked him a couple of peculiar questions, including, "Are you a stalker?"
An unidentified woman stepped in and told Lafferty, "We don't do this down here."
At that point, it appears McGraw grabbed the camera away from Lafferty and turned it off. Lafferty eventually got the camera back from a McGraw staffer.
The Morrisey campaign seized on the incident, which it labeled an "attack."
That's a stretch, since Lafferty was not physically harmed and no criminal charges have been filed.
