Why are Republicans in Congress so adamant about killing the Affordable Health Care Act? Because they know that once it is fully implemented they will not be able to fool people into believing that it is a bad program.
Republicans want to kill the Affordable Healthcare Act in its infancy because they know that once millions of Americans start to experience the benefits and realize how much better it is than what we had before, Obamacare will be with us forever. They coined the term "Obamacare" as a derogatory term, never realizing that we wouldn't take offense, but rather accept and own it as it gives Obama credit for it. Years from now, when even Republicans say "Don't mess with my Obamacare", Obama will be getting the credit for getting this country off that broken system we had before. If it hadn't been for Obama, millions would continue without healthcare insurance.
As it is, some Republicans already like some of the provisions in Obamacare - so imagine what will happen in 2014, when it goes full bloom?
