Is Daschle disqualified from representing South Dakota?

Tom Daschle may be disqualified from running for South Dakota’s seat in the Senate. This is because he bought a $2M house in D.C., and claimed homestead deduction there. So he may in fact not be considered a South Dakotan for the purpose of election, and S.D. law seems to say that a candidate must be a resident of the state.

I doubt whether this will be played out the way I desire to see. Still, I am hoping that Republican John Thune will unseat him.
