Republican Sen. Ron Gould, a Republican who sponsored the guns bill, said Brewer tacked to the right in the run-up to the 2010 election by signing the immigration law, known as SB1070, last spring. But now she's showing her true colors with her vetoes, he said.
"It's kind of disappointing because we're going to see this year that Brewer is not a conservative," he said.
By the numbers, Brewer's seven vetoes through Tuesday are far short of the total bills she signed.
"We've had a lot more signed than we've had lost," said Republican Rep. Andy Tobin, the House majority leader.
Brewer has signed bills creating a new voucher program for special education students, easing requirements to get a concealed-weapon permit, giving a tie-breaker adoption preference to married couples and restricting union activities.
Brewer also has yet to get an anti-abortion bill she won't sign.
Last month, she worked with Republican fiscal hawks on a budget-balancing plan that included deeper spending cuts and less gimmickry than she originally proposed.
"I don't think her overall politics have changed that much," said Rep. Daniel Patterson, a Tucson Democrat. "We've seen her sign far more bad legislation this year than we've seen her veto."
Patterson cited the new $8.3 billion budget.
The budget is largely built on a Medicaid spending cut that Brewer has proposed be accomplished by reducing enrollment by approximately 140,000 people through freezes on new signups for certain categories of low-income adults.
Brewer's relations with the Legislature's majority Republicans haven't always been smooth.
Brewer was Arizona's elected secretary of state when was elevated to the governor's office in January 2009 when Democrat Janet Napolitano resigned to serve in the Obama administration.
