ST. PAUL, Minn. (AP) - Details about what Minnesota insurance will cost to buy for 2015 through the state's online health exchange are being made public on Wednesday.

The Minnesota Department of Commerce announced Monday that officials will release information then, though it could be only a barometer.

That's because shoppers through the exchange called MNsure won't get precise premium and deductible information until they shop for plans that suit their unique situations. Some people are eligible for subsidies. Open enrollment starts Nov. 15.

The rates loom large in this fall's political campaigns. Static or reduced rates would be a sigh of relief to Democrats, who voted to create the virtual marketplace to comply with federal health law changes. Steep increases would give Republicans ammunition in campaigns for governor and the Legislature.
