With all of their effort to shift the blame, the truth is the Democrats own Obamacare. Republicans have never wanted it and never voted for it. Because of Obamacare's numerous flaws, Republicans have had 37 floor votes to improve Obamacare by taking out its dangerous parts. As a result, their efforts were rejected by the Democrats in the Senate. Knowing the disaster that Obamacare was, the Republicans sent up more bills to fully and partially repeal, defund, or dismantle Obamacare's worst parts. To say they have not worked to fix it, is fantasy. The truth is, they have always wanted no part of it.
Republican persistence has even been successful: 7 different bills have been signed into law that directly repeal or rescind funding from at least 8 different Obamacare provisions.
However, the Democrat-controlled Senate and the Obama Regime has never ever worked with the Republicans and even shut down the government to stonewall any effort at compromise and to hurt Republicans in the 2014 election cycle.
Because the Democrats have used Obamacare as a political battering ram to hurt Republican, they only have themselves to blame if Republicans let them swing in the wind with the Albatross Obamacare around their necks.
For a good summery of Republican efforts to fix Obamacare go here:
I am SO totally rooting for failure. I wouldn't lift a finger to "make this work". YMMV.
