(Bloomberg) -- Jeb Bush, like other Republican presidentialcandidates, is vowing to repeal the Patient Protection and Affordable CareAct, also known as Obamacare, while making healthcaremore innovative and affordable.

Bush's health care plan, outlined Monday in a two-page document,is light on details of how he'd change a system that accounts forabout 18 percent of the U.S. economy.

The former Florida governor said he wants to increaseinnovation, reduce the cost of care and give individual states morecontrol over how they take care of their citizens.

"ObamaCare is a government takeover of more than one-sixth ofthe American economy, and it epitomizes why Americans are so fed upwith Washington,'' Bush's document states. "To win on repeal,conservatives must unite around a vision of health care for thefuture—one that enables transformational innovation.''

About 9.9 million people get health coverage through theinsurance marketplaces set up by PPACA, with 8.4 million gettingsubsidies to buy policies.

The president's health reform law also expanded Medicaid coverage to more low-incomeindividuals, though some states have opted out of that part of thelaw.

To help individuals afford coverage, Bush wants to give peopletax credits to help them buy insurance. That's similar to PPACA,where individuals with low incomes can get government aid to buypolicies.

Bush's plan also emphasizes the use of health-savingsaccounts.

Bush also wants to tax some health premiums that are paid byemployers.

A similar initiative in the Patient Protection and AffordableCare Act, known as the Cadillac Tax, is facing repeal effortsfrom both Republican and Democratic legislators. It taxesemployer-paid premiums above a threshold, starting in 2018.

Democratic presidential candidates Hillary Clinton and BernieSanders have also focused on the affordability of health care, andthey've turned the high cost of some drugs into acampaign issue.

Bush also plans to put forth a separate plan forMedicare, the U.S. program for theelderly and disabled, according to the document releasedMonday.
