Dan Lungren, R-Calif., center, tours the soon-to-open University of California, Davis Comprehensive Cancer Center expansion with UC Davis Medical Center CEO Ann Madden Rice and cancer center director Ralph de Vere White, in Sacramento, Calif. Lungren is running for reelection for California's 3rd Congressional District against Democrat Ami Bera. Lungren knows what it's like to have a big bull's eye plastered on his back.
