Minnesota is edging closer to creating an online marketplace where more than a million people and small businesses will shop for health insurance. House members debated the Minnesota health insurance exchange bill late into the night Thursday, then passed it 72-61. Previously, House and Senate negotiators had worked out a final compromise on the exchange, which will change the way one out of every five Minnesotans shops for health insurance next year. The Senate will take up its version of the bill next week. The exchange is a key provision of the Obama administration's health care reforms.
