President Obama is hosting a meeting of the nation’s governors at the White House today amidst a contentious debate over the squeezing of workers’ rights and social services in the name of reducing deficits. At a gathering of the National Governors Association over the weekend, Democratic and Republican leaders agreed to form a committee to explore ways to amend Medicaid. The panel will look at how states can change eligibility rules and other provisions of the insurance program for low-income Americans. Republicans have called for converting Medicaid from an entitlement program to a block grant, similar to how Republicans and former President Bill Clinton altered welfare programs in the 1990s. Among the strongest advocates for that route is Wisconsin Gov. Scott Walker, who has just been named the new chair of the National Governors Association’s health and human services panel.
