Gov. Jan Brewer shocked the political world this week when she became the latest convert to President Barack Obama’s healthcare plan that both he and his critics refer to as “Obamacare.”

And later today, Brewer will again make her case as to why the 2010 Affordable Healthcare Act is good business for Arizona when she speaks today at a rally in Phoenix.

It was just two days ago that Brewer made the stunning announcement during her annual State of the State Address that kicked-off the 2013 legislative session.

It was a 180 degree turn for Brewer who’s been a constant critic of Obama and successfully campaigned against the president’s healthcare plan when she ran for election two years ago.

The governor will speak at the rally which begins at 2 p.m. today at the Maricopa Medical Center at 2601 E. Roosevelt St., Phoenix.

Brewer is setting herself up for potentially rough fight with many of her fellow Republicans at the Legislature who oppose Obama’s plan which requires the expansion of Medicaid.

In an effort to gain the support of business minded Republicans, Brewer is pitching it as an economic stimulus for the Arizona economy.

In a press release today the governor’s office says the expansion of Medicaid will, “generate nearly $8 billion in federal assistance for the state over three years, creating thousands of jobs and aiding rural and safety-net hospitals.”

If Brewer succeeds, about 300,000 of the state’s lowest income earners would get healthcare coverage through the Arizona Health Care Cost Containment System, the state’s Medicaid program.

Opponents of Obamacare say the country can’t afford it right now and will add to the mounting national debt.
