(CNN) - Republican Gov. Jan Brewer of Arizona easily won her party's gubernatorial nomination Tuesday night, according to a CNN projection.
Brewer captured 87 percent of the vote in the GOP primary election, according to early unofficial vote returns from the Associated Press.
At the time that she signed into law her state's controversial immigration measure, Brewer was involved in a competitive primary battle. But Brewer's political stock within Republican circles soared in the months after she put her signature to the bill, and two of her primary challengers dropped out of the contest.
Brewer will face off in November's general election against Arizona Attorney General Terry Goddard, who faced no opposition in the Democratic gubernatorial primary.
Brewer, Arizona's secretary of state in early 2009, became governor when Democratic Gov. Janet Napolitano stepped down after being confirmed as Secretary of Homeland Security in the Obama administration.
