Kansas Gov. Sam Brownback says he wants to wait until after the November presidential election to move forward on implementing a key part of the federal health care overhaul in his state.

The Republican governor said Thursday that the U.S. Supreme Court’s ruling upholding the 2010 law championed by Democratic President Barack Obama makes health care a political issue.

Opposition from Brownback and other Republicans who dominate the state Legislature has prevented Kansas from moving to set up an online marketplace for patients to shop for insurance policies. The federal law mandates those exchanges for each state by 2014.

States face a November deadline to tell federal officials of their plans. Brownback said that if GOP presidential nominee Mitt Romney unseats Obama, states will get a waiver from the requirement.
