When Sen. Ted Cruz of La Mancha jumped on his trusty steed and charged the windmills, he explained: “Everyone in America knows Obamacare is destroying the economy.” He added that accepting the Affordable Care Act would be like appeasing the Nazis.
Cruz is a smart man, and maybe this is just disingenuous demagoguery. But there's a scarier possibility: After spending too much time in the Republican echo chamber, he may believe what he says.
In the 1990s, as conservative talk radio spread across America, liberals felt victimized. But, in retrospect, the rise of talk radio, Fox News Channel and right-wing websites may have done greatest harm to conservatives themselves.
The right-wing echo chamber breeds extremism, intimidates Republican moderates and misleads people into thinking that their worldview is broadly shared.
That's the information bubble that tugs the entire Republican Party to the right and that transforms people like Cruz into crusading Don Quixotes. And that's why Republicans may lead us over a financial cliff, even though polling suggests that voters would blame them.
In one extreme case, the right-wing media bubble may even have been lethal for its inhabitants. That was the 2009-10 swine flu epidemic, which eventually killed up to 18,000 Americans, according to the Centers for Disease Control and Prevention.
When the flu first emerged, Republicans and Democrats responded with the same level of concern. That makes sense. Why should political differences affect our judgments about health? But then conservative commentators began to denounce the Obama administration's call for people to get vaccinated. Glenn Beck said he would do “the exact opposite” of what the federal government recommended. Rush Limbaugh said: If “you have some idiot government official demanding, telling me I must take this vaccine, I'll never take it.” Some on the left also voiced suspicion of the vaccine, but it was more common on right-wing shows to hear that flu vaccinations were a nefarious Obama plot.
