Former Rep. Mark Neumann (R-Wis.) has banked another high-profile endorsement in his primary battle against former four-term Gov. Tommy Thompson, with Sen. Pat Toomey (R-Pa.) saying Monday that he backs the conservative congressman.
"During his time in Congress, he fought for fiscal responsibility and common sense — even when that meant taking on members of his own party," Toomey said in a statement. "As a business owner who understands what it takes to create jobs, Mark will fight for hardworking American taxpayers."
Neumann and Thompson are vying to take on against Rep. Tammy Baldwin (D-Wis.) to replace the retiring Sen. Herb Kohl (D). Neumann has found some success running to the right of Thompson, taking 42 percent in a straw poll at the Wisconsin Republican convention in May, versus just 21 percent for the former governor. In addition to Toomey, Neumann has secured high-profile endorsements from prominent conservative lawmakers, including Sens. Jim DeMint (R-S.C.), Rand Paul (R-Ky.), Mike Lee (R-Utah) and Tom Coburn (R-Okla.), and organizations like the Club for Growth.
