BOSTON (CBS) – Former state treasurer Tim Cahill says he’s done with politics.

Cahill avoided further criminal prosecution last week, agreeing to pay a $100,000 civil fine for his role in misusing lottery ad funds under a deal reached with Attorney General Martha Coakley.

Coakley had charged Cahill with violating state law by spending $1.5 million on lottery ads down the stretch of his failed 2010 independent campaign for governor.

The deal was struck months after a jury was unable to reach a verdict in the criminal case against Cahill in December.

Speaking with Dan Rea on WBZ NewsRadio 1030’s Nightside Monday, Cahill was asked if he’d ever run for office again.

“I don’t think so. I don’t see any way. My wife would divorce me so, she’s more important to me than anything else.”

Rea also asked him what he and his wife would do if they ran into the Attorney General on the street:

“We don’t have any bitterness. We’re not haters and we would be respectful,” Cahill said. “It’s the golden rule and that’s what we live by and I’m sure she’d do the same thing.”

He continues to say he did nothing wrong running lottery ads during his campaign for governor, a campaign which he admits was dysfunctional.

Cahill is now working for a brokerage firm in Braintree.

As part of the agreement, Cahill has to pay the $100,000 fine out of his personal funds, and will not be allowed to use campaign funds to pay it off.

He does not have to pay off the fine immediately, but he will not be allowed to run for office until he does. Cahill will be allowed to keep his pension.
