Conservatives have to lie about this because it undercuts one of the essential raison d'etres of conservatism, which is the unsullied virtue of private institutions operating under capitalist principles free from government regulation. The financial crisis of 2008/2009 offers a direct contradiction of this conservative catechism.
In recent years a new big lie has emerged. It goes something like this: Obama and a Democratic Congress rammed through Obamacare in a purely partisan fashion that eschewed bipartisan cooperation. This has been one of the primary attacks against Obamacare from the hard Right, but interestingly it has also been a constant theme espoused by more moderate elements in attempting to explain why they opposed the recent attempt of the GOP to repeal and replace Obamacare with only GOP votes.
This view is based on the fact that Obamacare was passed in the Senate using reconciliation with only Democratic votes. However, the process that led to this was strikingly different from what we saw with recent GOP efforts to repeal and replace the ACA. As Glenn Kessler points out in a Washington Post fact checking column:
Republicans have skipped the lengthy, open process of hearings and markups of legislation that characterized the Democrats’ march to passage of the ACA. Instead, they moved directly to floor votes. Moreover, Democrats at first tried to enlist some Republican support, while Republicans have not reached out to Democrats.The part of the ACA legislative history that Republicans unanimously ignore is that Max Baucus, then chairman of the Senate Finance committee, worked diligently to try and gain the support of Olympia Snowe for the bill (Snowe voted for the bill in committee and later against the bill on the floor during the final vote). There was a serious and sustained effort to pass at least a minimally bipartisan bill. Obama and his Democratic allies in Congress did not want to pass a health care bill with only Democratic votes. The fact is that there was no GOP support for Obamacare not because Democrats wanted to ram through a partisan bill, but because Republicans had decided in advance to withhold cooperation on any major Obama initiative. This scorched earth policy of noncooperation was hatched even before Obama was inaugurated.
Comparing THIS process with the recent GOP votes on Obamacare repeal and replace is absurd. The Democrats tried to obtain GOP support and failed because the word had gone out that they were to obstruct major Obama initiatives, such as the stimulus and health care reform. Given this, the ONLY reason that Obamacare passed the Senate using reconciliation was that Scott Walker won Ted Kennedy's seat after he died of brain cancer and the Democrats lost their 60th vote. Reconciliation was a desperate last-minute fallback position after attempts at bipartisan cooperation failed. (It is worth noting that the major changes that Obamacare underwent during it path through Congress moved it closer to--not further from--the GOP position. In particular, the public option and an expansion of Medicare to those 55 and older were dropped.) Contrast this with the GOP efforts on repeal and replace. Reconciliation with a purely partisan bill was the ONLY option ever tried. It was the first choice (and so far only choice) of the Republican Congress. It wasn't forced on them. It was their preference.
