Why are liberals so condescending?

Not all, but a significant number are in one or more of these four ways: [Link]

The first is the "vast right-wing conspiracy," a narrative made famous by Hillary Rodham Clinton but hardly limited to her. This vision maintains that conservatives win elections and policy debates not because they triumph in the open battle of ideas but because they deploy brilliant and sinister campaign tactics. A dense network of professional political strategists such as Karl Rove, think tanks such as the Heritage Foundation and industry groups allegedly manipulate information and mislead the public. Democratic strategist Rob Stein crafted a celebrated PowerPoint presentation during George W. Bush's presidency that traced conservative success to such organizational factors.
This liberal vision emphasizes the dissemination of ideologically driven views from sympathetic media such as the Fox News Channel. For example, Chris Mooney's book "The Republican War on Science" argues that policy debates in the scientific arena are distorted by conservatives who disregard evidence and reflect the biases of industry-backed Republican politicians or of evangelicals aimlessly shielding the world from modernity. In this interpretation, conservative arguments are invariably false and deployed only cynically. Evidence of the costs of cap-and-trade carbon rationing is waved away as corporate propaganda; arguments against health-care reform are written off as hype orchestrated by insurance companies.
This worldview was on display in the popular liberal reaction to the Supreme Court's recent ruling in Citizens United v. Federal Election Commission. Rather than engage in a discussion about the complexities of free speech in politics, liberals have largely argued that the decision will "open the floodgates for special interests" to influence American elections, as the president warned in his State of the Union address. In other words, it was all part of the conspiracy to support conservative candidates for their nefarious, self-serving ends.
It follows that the thinkers, politicians and citizens who advance conservative ideas must be dupes, quacks or hired guns selling stories they know to be a sham. In this spirit, New York Times columnist Paul Krugman regularly dismisses conservative arguments not simply as incorrect, but as lies. Writing last summer, Krugman pondered the duplicity he found evident in 35 years' worth of Wall Street Journal editorial writers: "What do these people really believe? I mean, they're not stupid -- life would be a lot easier if they were. So they know they're not telling the truth. But they obviously believe that their dishonesty serves a higher truth. . . . The question is, what is that higher truth?"
In Krugman's world, there is no need to take seriously the arguments of "these people" -- only to plumb the depths of their errors and imagine hidden motives.
But, if conservative leaders are crass manipulators, then the rank-and-file Americans who support them must be manipulated at best, or stupid at worst. This is the second variety of liberal condescension, exemplified in Thomas Frank's best-selling 2004 book, "What's the Matter With Kansas?" Frank argued that working-class voters were so distracted by issues such as abortion that they were induced into voting against their own economic interests. Then-Vermont Gov. Howard Dean, later chairman of the Democratic National Committee, echoed that theme in his 2004 presidential run, when he said Republicans had succeeded in getting Southern whites to focus on "guns, God and gays" instead of economic redistribution.
And speaking to a roomful of Democratic donors in 2008, then-presidential candidate Obama offered a similar (and infamous) analysis when he suggested that residents of Rust Belt towns "cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations" about job losses. When his comments became public, Obama backed away from their tenor but insisted that "I said something that everybody knows is true."
In this view, we should pay attention to conservative voters' underlying problems but disregard the policy demands they voice; these are illusory, devoid of reason or evidence. This form of liberal condescension implies that conservative masses are in the grip of false consciousness. When they express their views at town hall meetings or "tea party" gatherings, it might be politically prudent for liberals to hear them out, but there is no reason to actually listen.

The third version of liberal condescension points to something more sinister. In his 2008 book, "Nixonland," progressive writer Rick Perlstein argued that Richard Nixon created an enduring Republican strategy of mobilizing the ethnic and other resentments of some Americans against others. Similarly, in their 1992 book, "Chain Reaction," Thomas Byrne Edsall and Mary D. Edsall argued that Nixon and Reagan talked up crime control, low taxes and welfare reform to cloak racial animus and help make it mainstream. It is now an article of faith among many liberals that Republicans win elections because they tap into white prejudice against blacks and immigrants.
Race doubtless played a significant role in the shift of Deep South whites to the Republican Party during and after the 1960s. But the liberal narrative has gone essentially unchanged since then -- recall former president Carter's recent assertion that opposition to Obama reflects racism -- even though survey research has shown a dramatic decline in prejudiced attitudes among white Americans in the intervening decades. Moreover, the candidates and agendas of both parties demonstrate an unfortunate willingness to play on prejudices, whether based on race, region, class, income, or other factors.
Finally, liberals condescend to the rest of us when they say conservatives are driven purely by emotion and anxiety -- including fear of change -- whereas liberals have the harder task of appealing to evidence and logic. Former vice president Al Gore made this case in his 2007 book, "The Assault on Reason," in which he expressed fear that American politics was under siege from a coalition of religious fundamentalists, foreign policy extremists and industry groups opposed to "any reasoning process that threatens their economic goals." This right-wing politics involves a gradual "abandonment of concern for reason or evidence" and relies on propaganda to maintain public support, he wrote.
