Sean Duffy wins big in Wisconsin's 7th district

*
Sean Duffy has won the GOP Primary in Wisconsin's 7th Congressional District by a wide margin and will face Democrat state Sen. Julie Lassa in the general election:

The winner will succeed Rep. David Obey (D-Wis.).

Lassa easily defeated Don Raihala of Superior for a shot at the seat held for more than four decades by Obey.

Duffy, a former Ashland County district attorney, beat Daniel Mielke for the Republican nomination while Lassa, a state senator, outdistanced Don Raihala, a Democrat from Superior.

With roughly half of the precincts reporting, Duffy, who was endorsed by Sarah Palin, captured 68 percent of the vote to Mielke's 32 percent.
