ST. PAUL -- Gov. Mark Dayton's declaration that the federal health law is "no longer affordable" for many Minnesota residents could spark major health care changes.

The Democratic governor's remarks last week set off more talk of a special session to address rising costs and concerns about market stability. Premiums are set to rise between 50 percent and 67 percent for shoppers buying individual coverage next year.

But there are plenty of ideas swirling and little agreement between the two parties who control the Legislature. A state rebate could help offset increases for those who don't get federal subsidies. A long-term program to help insurers cover the sickest enrollees is another option, but the funding mechanism is unclear.

Dayton says he's won't entertain a special session until after the election.
