U.S. House Republicans on Friday won passage of a measure starting the process of dismantling Obamacare, despite concerns about not having a ready replacement and the potential financial cost of repealing repealing Democratic President Barack Obama’s landmark health insurance law. The House of Representatives voted 227-198 to instruct committees to draft legislation by a target date of Jan. 27 that would repeal the 2010 Affordable Health Care Act, popularly known as Obamacare.
