A Sacramento, Calif., judge on Tuesday refused to fast-track hearings in a suit challenging Democrat Jerry Brown’s qualifications to be attorney general, a ruling that likely eliminates the plaintiffs’ best chance of ensuring a Republican wins the Nov. 7 election.

Superior Court Judge Shelleyanne Chang’s decision means the plaintiffs, five county GOP leaders, face the difficult task of persuading a judge to bar Brown from office if he wins the election. The Republicans’ attorney, Charles Bell, said his clients will challenge the election results if Brown wins.
