Governor Dayton signs the controversial “Health Insurance Exchange” bill into law this (WED) morning at the Capitol. The online health insurance marketplace is a key part of President Obama’s Affordable Care Act. It will allow around 1.2-million Minnesotans to choose from health insurance policies pre-screened by a special board. Democrats say competition for such a large pool of customers will force prices down, but detractors note that most of the anticipated savings will come from federal subsidies. Republicans warn it’s a step toward government-controlled health care, and that four people on a special board will be able to decide what insurance policies are available to over one-fifth of Minnesotans.
