Hundreds of people rallied at the Texas State Capitol in Austin on Tuesday to oppose Gov. Rick Perry’s rejection of federal Medicaid assistance. Perry announced last year he would refuse billions of dollars in federal funding rather than accept the Medicaid expansion mandated under President Obama’s healthcare reform law. Texas has the highest percentage of uninsured people in the country, with nearly a quarter of its population, or 6.2 million people, lacking health insurance. Although a number of other Republican governors also initially vowed to reject Medicaid expansion, at least two — Chris Christie of New Jersey and Rick Scott of Florida — have since changed course by vowing to opt in and accept federal help.
