The Kansas Supreme Court has ordered the state to remove U.S. Senate Democratic nominee Chad Taylor’s name from the ballot, in a ruling that could influence the national fight for control of the Senate.

The court’s decision Thursday leaves Democrats without a nominee, potentially making it easier for independent candidate Greg Orman to defeat three-term Republican incumbent Sen. Pat Roberts. The GOP has counted on Roberts winning re-election on Nov. 4 as they seek to recapture a Senate majority.

Taylor withdrew from the race to avoid a split of anti-Roberts votes. But Republican Secretary of State Kris Kobach, who backs Roberts, declared that Taylor didn’t fully comply with a state election law in submitting his letter of withdrawal.
