In his Akron stop on a statewide listening tour, U.S. Sen. Sherrod Brown surrounded himself with skeptics of the Republican plan to repeal and replace the Affordable Care Act, or “Obamacare.”

The Cleveland Democrat has been kept in the dark as about a dozen conservatives in the U.S. Senate meet privately to consider a plan passed earlier in the month by the U.S. House. If accepted as is, the plan would result in 20 percent higher insurance premiums and 14 million Americans losing coverage by 2018, according to research published last week by the nonpartisan Congressional Budget Office (CBO).

That report has soured public opinion on the GOP plan. A poll of 1,205 adults conducted this month by the Kaiser Family Foundation found that 49 percent approve of the Affordable Care Act and 31 percent prefer the GOP repeal plan. Only 1 in 10 said the Senate should pass the GOP plan without making changes.

House Republicans passed the American Health Care Act, as their plan is called, before the CBO could score it.
