ATLANTA (AP/WAOK) - Georgia Gov. Nathan Deal says President Barack Obama’s health care overhaul is the largest tax increase in the U.S. history.

The Republican governor said Thursday that his administration may wait until the November elections before implementing parts of the law. GOP leaders are hoping that if Republican Mitt Romney wins the White House and Republicans take Congress, the health care law could be overturned.

Deal said his administration may ask the federal government for more time to decide whether Georgia will implement its own health insurance exchange or whether it wants the federal government to do it.

The Supreme Court’s ruling gave states the option to decide whether to expand health care coverage in their Medicaid programs. Deal said it was too early to say whether Georgia would participate.
