Harshbarger emerged as Cellucci's rival after winning a three-way Democratic primary for governor. Cellucci also was boosted by Democratic defections, but Harshbarger closed sharply at the end, in part by criticizing Big Dig costs. In a late-October debate, he challenged Cellucci to "tell the truth" about his budget proposals.
Cellucci, a movie buff, shot back with a line made famous by Jack Nicholson in "A Few Good Men."
The acting governor said: "You can't handle the truth."
Harshbarger closed his e-mail with one more jab at his former rival.
"I hope my 1998 campaign chair now gets the benefit of the 'truth' Cellucci claimed, in his inimitable way, 'we just couldn't handle!'" he wrote.
