The state has applied for millions of dollars in federal funding to establish a health insurance exchange. But plans to spend the money will still need approval from the Republican-dominated Idaho Legislature, where lawmaker hatred of the 2010 health care overhaul doomed a previous effort to allocate federal money toward helping set up a statewide exchange. States must establish insurance exchanges under the Patient Protection and Affordable Care Act. The Idaho House Health and Welfare Committee discussed Idaho's exchange plans on Thursday.  Some lawmakers are already vowing to fight plans to spend the money.
