Here are some thoughts on where things stand in the aftermath of the certain passage of the Senate health-care bill.

1. Few Democrats understand the depth and intensity of opposition that exists toward them and their agenda, especially regarding health care. Passage of this bill will only heighten the depth and intensity of the opposition. We’re seeing a political tsunami in the making, and passage of health-care legislation would only add to its size and force.

2. This health-care bill may well be historic, but not in the way the president thinks. I’m not sure we’ve ever seen anything quite like it: passage of a mammoth piece of legislation, hugely expensive and unpopular, on a strict party-line vote taken in a rush of panic because Democrats know that the more people see of ObamaCare, the less they like it.

3. The problem isn’t simply with how substantively awful the bill is but how deeply dishonest and (legally) corrupt the whole process has been. There’s already a powerful populist, anti-Washington sentiment out there, perhaps as strong as anything we’ve seen. This will add kerosene to that raging fire.

4. Democrats have sold this bill as a miracle-worker; when people see first-hand how pernicious health-care legislation will be, abstract concerns will become concrete. That will magnify the unhappiness of the polity.

5. The collateral damage to Obama from this bill is enormous. More than any candidate in our lifetime, Obama won based on the aesthetics of politics. It wasn’t because of his record; he barely had one. And it wasn’t because of his command of policy; few people knew what his top three policy priorities were. It was based instead on the sense that he was something novel, the embodiment of a “new politics” – mature, high-minded and gracious, intellectually serious. That was the core of his speeches and his candidacy. In less than a year, that core has been devoured, most of all by this health-care process.

Mr. Obama has shown himself to be a deeply partisan and polarizing figure. (“I have never been asked to engage in a single serious negotiation on any issue, nor has any other Republican,” Senator McCain reported over the weekend.) The lack of transparency in this process has been unprecedented and bordering on criminal. The president has been deeply misleading in selling this plan. Lobbyists, a bane of Obama during the campaign, are having a field day.

President Obama may succeed in passing a terribly unpopular piece of legislation – but in the process, he has shattered his carefully cultivated image. It now consists of a thousand shards.

6. This health-care bill shouldn’t be seen in isolation. It’s part of a train of events that include the stimulus package, the omnibus spending bill (complete with some 8,500 earmarks), and a record-sized budget. In addition, as Jim Manzi points out in the new issue of National Affairs:

[Under Obama] the federal government has also intervened aggressively in both the financial and industrial sectors of the economy in order to produce specific desired outcomes for particular corporations. It has nationalized America’s largest auto company (General Motors) and intervened in the bankruptcy proceedings of the third-largest auto company (Chrysler), privileging labor unions at the expense of bondholders. It has, in effect, nationalized what was America’s largest insurance company (American International Group) and largest bank (Citigroup), and appears to have exerted extra-legal financial pressure on what was the second-largest bank (Bank of America) to get it to purchase the ­country’s largest securities company (Merrill Lynch). The implicit government guarantees provided to home-loan giants Fannie Mae and Freddie Mac have been called in, and the federal government is now the largest de facto lender in the residential real-estate market. The government has selected the CEOs and is setting compensation at major automotive and financial companies across the country. On top of these interventions in finance and commerce, the administration and congressional Democrats are also pursuing both a new climate and energy strategy and large-scale health-care reform. Their agenda would place the government at the center of these two huge sectors of the economy…

Together, these actions tell quite a tale. Mr. Obama has revived the worst impressions of the Democratic party – profligate and undisciplined, arrogant, lovers of big government, increasers of taxes. The issues and narrative for American politics in the foreseeable future has been set — limited government versus exploding government, capitalism versus European style socialism, responsible and measured policies versus reckless and radical ones.

Barack Obama is in the process of inflicting enormous damage to his presidency and his party. And there is more, much more to come.
