The republicans had an entire presidential election to detail exactly why Obamacare is a bad thing that needs to be repealed. They were covered by every single media outlet, major or otherwise, and to me, they really did a great job getting across the message that "we need to repeal Obamacare", but then they proceeded to make it very clear that none of the presidential candidates really knew enough about the law to know why we need to repeal it. The problem has less to do with the republican party than it does with the people that they put on the national stage.
