The Senate Republican primary in Nebraska has turned into a proxy war between conservatives and establishment Republicans that could complicate efforts to wrest control of the Senate from Democrats.
Sen. Jim DeMint (R-S.C.), a leading voice for Tea Party conservatives in Washington, has made an aggressive bid to defeat Jon Bruning, the front-runner in the primary, because of lingering doubts about his commitment to conservative principles.
DeMint has stuck fast to his claim that he would prefer to serve with 30 Republicans in the mold of Sen. Marco Rubio (R-Fla.), a rising conservative star, than with 60 Republicans like former Sen. Arlen Specter (Pa.), who joined Democrats in 2009 before losing reelection.
