South Dakota State Senator in Sex Scandal, Guess Which Party He's In?

In this AP story which I spotted on FoxNews.com, the wire's reporter Chet Brokaw sums up the story of South Dakota state senator Dan Sutton of Flandreau, who's mired in allegations of improper behavior with an 18-year-old male page. You can read the story for all the details if you're interested, but what I wanted to point out was the party affiliation of the Senator. Care to guess? If you said "Democrat", you're right. And where does that information appear? Why, in the very last sentence, of course.

I was unable to learn anything about Chet Brokaw, but given the last name, and given that Tom Brokaw is a native of, and still has ties to, South Dakota, is Chet a relative of the former NBC anchorman? Does anyone know?
