They are definitely trying to blame Obama as much as possible... As "he's the one who won't negotiate". 
Despite the fact that the Anerican voters chose to vote this bill into law, the republicans still think they know best and that they can block the wishes of the American people. Sadly, I don't think it'll have any effect on the next election, and the republicans stand a very real chance of being elected. 
Fwiw, it's not even nationalised healthcare that they're trying to implement. It's just making it mandatory to have health insurance and making insurers lower premiums and not reject people based on pre-existing conditions.
Since it costs almost $10,000 to give birth in the US without insurance, not including any prenatal doctors visits, and, as a hospital won't turn a woman in labour away, even if she can't afford that bill, it means higher health care costs are passed on to everyone else, resulting in even more people not being able to afford their bills, etc., etc.
It's a common sense bill and one that is long overdue. Shame on the entire Republican Party for yet again, ignoring what the people want and need in favour of pushing their own agenda through (oil pipeline).
