myself and my colleagues spent the day asking members, is this a huge concern you don't know what these new additions to this proposal will actually do? take a listen. >> how do you explain to constituents the fact republicans will have voted on this bill without a full cbo score, we only have a score on the original bill? >> the three amendments that are new aren't going to change dramatically that cbo score, so the basic cbo score is going to still be in the ballpark. everything else we said either expands coverage, takes care of preexisting conditions or lowers premiums, every amendment added is a good move. >> how do you know this is going to be right given there is no cbo analysis to say how many people lose coverage and the impact this would have on the economy? >> i know we're doing the right thing. >> reporter: but how? >> i know. >> that's putting a lot of faith
