A Kansas House committee has endorsed two separate proposals aimed at keeping parts of the new federal health care law from taking effect in the state. Thursday's votes in the Health and Human Services Committee advanced the so-called health care "freedom" measures to the entire House. One proposal would amend the Kansas Constitution to declare that no person or employer can be forced to buy health insurance - challenging a federal mandate that most Americans buy health insurance starting in 2014. But the proposed amendment wouldn't go to voters until November 2012. That led to the other measure, a proposed law along similar lines that would take effect within two weeks of being signed by the governor. On Monday, a judge in Florida struck down the federal law.
