Business interests, Brewer push for implementation of health care exchange 

Arizona’s policymakers clashed with members of the business community and insurance industry Nov. 2 over whether to implement a key component of the federal health care overhaul. Under the federal law, states have the option to run their own health insurance exchange, which will ultimately be a web portal where individuals and businesses can buy insurance. If states choose not to implement the exchanges, the federal government will do it for them.
