Fifteen-term Rep. F. James Sensenbrenner Jr., a Wisconsin Republican, has rarely faced a serious challenge during a long House career in a stretch of suburban Milwaukee where Republican voters dominate. But Sensenbrenner, in the 2008 campaign, is being double-teamed by Republican Jim Burkee and Democrat Jeff Walz, friends and teaching colleagues at the district's Concordia University -- who are staging a rare tandem challenge to the incumbent.
Burkee plans to run against Sensenbrenner in the September 2008 Republican primary in Wisconsin's 5th Congressional District, while Walz seeks to claim the usually uncoveted Democratic nomination in a place where 63 percent of the voters favored re-electing George W. Bush as president in 2004.
