There has been a fascinating sea-change in President Obama's rhetoric over the last year. He ran for office, and began his presidency, making his case in largely non-ideological terms, as a defense of pragmatism and against ideology. As Republicans have met him with a stone wall of resistance, the idealistic tinge of his rhetoric has largely disappeared. Now Obama contrasts himself with the partisanship ideological extremism of the Republican Party. Here is his speech yesterday in Pittsburgh:

Before I was even inaugurated, the congressional leaders of the other party got together and made a calculation that if I failed, they’d win. So when I went to meet with them about the need for a Recovery Act, in the midst of crisis, they announced they were against it before I even arrived at the meeting.  Before we even had a health care bill, a Republican senator actually said, “If we’re able to stop Obama on this, it will be his Waterloo.  It will break him.”  So those weren’t very hopeful signs.       
But to be fair, a good deal of the other party’s opposition to our agenda has also been rooted in their sincere and fundamental belief about the role of government.  It’s a belief that government has little or no role to play in helping this nation meet our collective challenges.  It’s an agenda that basically offers two answers to every problem we face:  more tax breaks for the wealthy and fewer rules for corporations. 
The last administration called this recycled idea “the Ownership Society.”  But what it essentially means is that everyone is on their own.  No matter how hard you work, if your paycheck isn’t enough to pay for college or health care or childcare, well, you’re on your own.  If misfortune causes you to lose your job or your home, you’re on your own.  And if you’re a Wall Street bank or an insurance company or an oil company, you pretty much get to play by your own rules, regardless of the consequences for everybody else.

Obama then explained how he understands the primacy of the private sector for wealth creation and that "government doesn't have all the answers." At that point, though, he launched a robust defense of government along with a pointed contrast with the failures of Republican governance:

But I also understand that throughout our nation’s history, we have balanced the threat of overreaching government against the dangers of an unfettered market.  We've provided a basic safety net, because any one of us might experience hardship at some time in our lives and may need some help getting back on our feet.  And we've recognized that there have been times when only government has been able to do what individuals couldn't do and corporations wouldn't do.
That's how we have railroads and highways, public schools and police forces.  That's how we've made possible scientific research that has led to medical breakthroughs like the vaccine for Hepatitis B, and technological wonders like GPS.  That's how we have Social Security and a minimum wage, and laws to protect the food we eat and the water we drink and the air that we breathe.  That’s how we have rules to ensure that mines are safe and, yes, that oil companies pay for the spills that they cause. 
Now, there have always been those who’ve said no to such protections; no to such investments.  There were accusations that Social Security would lead to socialism, and that Medicare was a government takeover.  There were bankers who claimed the creation of federal deposit insurance would destroy the industry.  And there were automakers who argued that installing seatbelts was unnecessary and unaffordable.  There were skeptics who thought that cleaning our water and our air would bankrupt our entire economy.  And all of these claims proved false.  All of these reforms led to greater security and greater prosperity for our people and our economy. 
So what was true then is true today.  As November approaches, leaders in the other party will campaign furiously on the same economic arguments they’ve been making for decades.  Fortunately, we don't have to look back too many years to see how their agenda turns out.  For much of the last 10 years we've tried it their way.  They gave us tax cuts that weren’t paid for to millionaires who didn’t need them.  They gutted regulations and put industry insiders in charge of industry oversight.  They shortchanged investments in clean energy and education, in research and technology.  And despite all their current moralizing about the need to curb spending, this is the same crowd who took the record $237 billion surplus that President Clinton left them and turned it into a record $1.3 trillion deficit.
So we know where those ideas lead us.  And now we have a choice as a nation.  We can return to the failed economic policies of the past, or we can keep building a stronger future.

I'm especially interested in Obama's invocation of the history of right-wing attacks on major social reform. TNR published a longer version of this list a few months ago. It's a powerful indictment of the failure of right-wing ideology. Here's what I wrote last December:

In the right-wing mind, the world we live in at any given moment can be described as the free market, the American way of life, perhaps not a perfect world but a cherished and fundamentally free one. The next advance of liberalism will always bring socialism, tyranny, a crushing burden on industry, and other horrors. The previous liberal advances that they or their predecessors greeted with such hysteria are eventually incorporated into the landscape of the free American way of life.
Everything that the 1960s right said about Medicare, the contemporary right no longer believes, while fervently believing it will all hold true of health care reform. Similarly, the hysteria of the 1970s right about clean-air regulation no longer plagues the contemporary right, but it grips conservatives when it comes to greenhouse-gas regulation. (Charles Krauthammer: Cap-and-trade “will destroy what’s left of the industrial Midwest.”) And so it goes.
