Talking Points Memo notes that Arizona Chamber of Commerce and Industry is airing a 30-second ad to back up Gov. Jan Brewer's push to expand Medicaid in Arizona:

The ad was launched by Restoring Arizona, a group tied to the Arizona Chamber of Commerce and Industry and which has been promoting the Republican governor's decision to expand Medicaid as part of the Affordable Care Act. The group said it planned to run the ad statewide.

"Gov. Brewer's conservative plan will keep our state's budget balanced while providing quality health care to Arizona's citizens so we can focus our budget on what matters most, like education, public safety and growing our economy," the narrator said in the spot. It closed by urging Arizonans to contact their legislators to pledge support for Brewer's "fiscally conservative Medicaid plan."

Along with skeptical Republican lawmakers, Brewer is facing opposition from the massive and well-funded conservative advocacy group Americans For Prosperity. Brewer's decision in January to accept the Medicaid expansion under President Barack Obama's new federal health care law was viewed by many as a surprise, but she defended the move on both moral and economic grounds.
