TAMPA, Fla. (AP) - A GOP committee has outlined a party platform with positions on key social and entitlement issues far more strict than the presidential candidate they plan to nominate next week.

The platform panel of the Republican National Committee voted to propose a constitutional amendment outlawing abortion without specific exceptions for rape or incest. That's at odds with the position of presumptive nominee Mitt Romney, who supports abortion in the event of rape.

The platform committee also adopted a position on Medicare that supports turning the federal health insurance program for seniors into a voucher-like system. That position is more in line with Romney's running mate, Wisconsin congressman Paul Ryan.

Virginia Gov. Bob McDonnell, chairman of the RNC's Committee on Resolutions, said the platform "reflects the views of the grassroots leaders of the Republican Party."

The platform is set to be adopted Monday by the RNC.
