BY RICARDO ALONSO-ZALDIVAR AND BOB CHRISTIE Associated Press WASHINGTON, D.C. — It’s Republican versus Republican in the latest round of political battles over health care. Conservative Republican leg islators in major states are trying to block efforts by more prag matic governors of their own party to accept health insurance for more low-income residents under President Barack Obama’s health care law. Unlike their congressional counterparts, who’ve misfired in repeated attempts to torpedo the law, state Republicans may well sink the expansion of Medicaid in populous states such as Florida and Michigan. That would mean leaving billions of dollars in federal matching funds on the table and hundreds of thousands of the poor uninsured. Expansion opponents said it’s an issue that goes to their core beliefs. “It’s an ideological principle piece to us on the conservative side,” said state Rep. David Gowan, majority leader in the Arizona House of Representa tives. “We don’t believe in the expansion of Medicaid itself it’s within the process of man dating health care. We don’t believe it’s the government’s duty to do that. It should be open for people to go get their health care.” Nine Republican governors supported or accepted the Med icaid expansion, a major compo nent of the health care law tak ing effect Jan. 1.
