On 710 KIRO, Dori Monson interviewed Mike McGavick just now about his drunken driving arrest. McGavick's spokesman said last week that McGavick wouldn't be talking about his 1993 DUI again in the campaign.

But Monson put McGavick through some tough but polite questions about discrepancies in the candidate's mea culpa and details that emerged with released of the police report.

McGavick said there was no attempt to mislead anyone and that his campaign tried to get the police report but was unable to find any records about the arrest that police in Maryland released to the media last week. He said if he had remembered all the details he would have included them in his open letter to voters.

"Why wouldn't I have? I wanted this out. I just said what I believed had happened and I was wrong on a couple of details, and I'm sorry that I was wrong on a couple of details."

Monson asked McGavick if he still drinks. "I enjoy a drink. Drink too much and drive? No. No, I will not," McGavick said.

But Monson pressed him on that, asking if he drives after drinking at all.

"Social drinking is a part of my life," McGavick said.

But why not have a zero tolerance policy about drinking and driving?

"Because I don't have any risk that I won't follow what I know is right. So, I don't feel the need to do that. The law takes all this into account, Dori."

Also, last week Washington Post political blogger Chris Cillizza wrote that McGavick's confession is the sort of thing that could make or break a campaign. Today, he says "break" looks more likely.

If you are going to confess past foibles in the context of a political campaign, you need to put everything on the table -- not offer it up in bits and pieces. McGavick still has a chance to unseat Maria Cantwell (D), but it has diminished over the past week.

UPDATE: McGavick isn't just answering questions, he clearly seems to want to say more about the DUI and the fallout from release of the police report. He just sent this e-mail message to supporters:

Friends,

I want to take a minute to reach out to you with a couple of thoughts.

Recently, I told you all in an open letter on my blog that one of my biggest mistakes in life was a DUI some 13 years ago. Granted, this disclosure was an unconventionally honest approach to politics, but I want to be candid with voters about my mistakes and the lessons I've learned.

I did not have a written record of the event, and I am not a lawyer. I relied only on my memory of a 13-year-old event. A copy of the police report has now been published, and it shows that I had two details wrong. I said I cut a yellow light too close, while the officer reported that the light was red. I said I had been cited, while the report says that I was both cited and arrested. I don't believe that most citizens will consider these differences to be key in judging my integrity.

I believed, and still believe, that the relevant points were that I had way too much to drink and that I got a DUI. I think that was pretty straightforward. In fact, some people said it was "too much information"!

I've been candid with reporters all along, and I apologize if anyone felt I misled themâ€"clearly, that was not my intent.

To my supporters and the curious, I'm sorry that we have all been distracted from the real issues facing our state. I first raised the issue of my past mistakes because I believe in running a different kind of campaign. Candidates shouldn't be afraid to admit that they are human and to talk about lessons they've learned. Even with the media attention surrounding this embarrassing event, I still believe in campaigning in this open and straightforward way.

I believe Washingtonians are hungry for something different. They are tired of the politics of character assassination. The people of this state are looking for a candidate who offers change, who is willing to admit imperfection.

I look forward to debating the very serious issues that face us. Together, we're going to change the policies and politics of this country for the better!
