chris: limits draw down on political differences on obamacare. one is how to help lower-income people pay for insurance, people who aren't covered by medicaid. there is an idea of refundable tax credits. some conservative people say it's just another name for subjects does. there is also the question about the 11 million people who gain coverage under the expansion medicaid. what happens to them? those are size and issues. >> it's always hard when you pull back on entitlements. when obama came in 2008 he passed obamacare without a single republican vote. now it's such a mess of legislation. you pull one stick out and it all falls apart. a lot of conservatives are calling into my radio show.
