The Morrisey camp wants voters to equate McGraw's actions to that of his brother, Warren McGraw, during a labor rally at Racine in 2004.
Warren McGraw, then a state Supreme Court Justice running for re-election, delivered an unhinged and paranoid rant that contributed to his defeat.
Darrell McGraw is an idiosyncratic man.
His supporters - and there have been enough to elect him to state Supreme Court once and the Attorney General's Office five times - see him as an intellectually gifted advocate.
His detractors criticize him for using money from legal settlements to promote himself and his office.
McGraw has a race on his hands this time. Morrisey has raised enough money to mount a viable statewide campaign.
But Morrisey is frustrated that McGraw won't debate him. Morrisey says if McGraw would meet him on the debate platform, he would pull the tracker.
Embarrassing moments caught on video can make a difference, especially in a close race.
In 2006, Republican George Allen narrowly lost to Democrat Jim Webb in the U.S. Senate race in Virginia after video surfaced of Allen singling out the Webb tracker in the crowd and calling the young man of Indian heritage "Macaca."
In Milton, McGraw's camera grab wasn't a "Macaca Moment," and it doesn't rise to the level of the "Rant in Racine."
What it does show is the attorney general of the state losing his cool under pressure, and behaving in a way that is unbecoming to the office and embarrassing to him personally.
