John P. Judis sums up  the modern GOP this way:
"Over the last four decades, the Republican Party has transformed from a loyal opposition into an insurrectionary party that flouts the law when it is in the majority and threatens disorder when it is the minority. It is the party of Watergate and Iran-Contra, but also of the government shutdown in 1995 and the impeachment trial of 1999. If there is an earlier American precedent for today's Republican Party, it is the antebellum Southern Democrats of John Calhoun who threatened to nullify, or disregard, federal legislation they objected to and who later led the fight to secede from the union over slavery."
A couple of years ago, a Republican committee staff director told me candidly (and proudly) what the method was to all this obstruction and disruption. Should Republicans succeed in obstructing the Senate from doing its job, it would further lower Congress's generic favorability rating among the American people. By sabotaging the reputation of an institution of government, the party that is programmatically against government would come out the relative winner.
A deeply cynical tactic, to be sure, but a psychologically insightful one that plays on the weaknesses both of the voting public and the news media. There are tens of millions of low-information voters who hardly know which party controls which branch of government, let alone which party is pursuing a particular legislative tactic. These voters' confusion over who did what allows them to form the conclusion that "they are all crooks," and that "government is no good," further leading them to think, "a plague on both your houses" and "the parties are like two kids in a school yard." This ill-informed public cynicism, in its turn, further intensifies the long-term decline in public trust in government that has been taking place since the early 1960s - a distrust that has been stoked by Republican rhetoric at every turn ("Government is the problem," declared Ronald Reagan in 1980).
The media are also complicit in this phenomenon. Ever since the bifurcation of electronic media into a more or less respectable "hard news" segment and a rabidly ideological talk radio and cable TV political propaganda arm, the "respectable" media have been terrified of any criticism for perceived bias. Hence, they hew to the practice of false evenhandedness. Paul Krugman has skewered  this tactic as being the "centrist cop-out." "I joked long ago," he says, "that if one party declared that the earth was flat, the headlines would read 'Views Differ on Shape of Planet.'"
Inside-the-Beltway wise guy Chris Cillizza merely proves Krugman right in his Washington Post analysis of "winners and losers" in the debt ceiling impasse. He wrote  that the institution of Congress was a big loser in the fracas, which is, of course, correct, but then he opined: "Lawmakers - bless their hearts - seem entirely unaware of just how bad they looked during this fight and will almost certainly spend the next few weeks (or months) congratulating themselves on their tremendous magnanimity." Note how the pundit's ironic deprecation falls like the rain on the just and unjust alike, on those who precipitated the needless crisis and those who despaired of it. He seems oblivious that one side - or a sizable faction of one side - has deliberately attempted to damage the reputation of Congress to achieve its political objectives.
This constant drizzle of "there the two parties go again!" stories out of the news bureaus, combined with the hazy confusion of low-information voters, means that the long-term Republican strategy of undermining confidence in our democratic institutions has reaped electoral dividends. The United States has nearly the lowest voter participation among Western democracies; this, again, is a consequence of the decline of trust in government institutions - if government is a racket and both parties are the same, why vote? And if the uninvolved middle declines to vote, it increases the electoral clout of a minority that is constantly being whipped into a lather by three hours daily of Rush Limbaugh or Fox News. There were only 44 million Republican voters in the 2010 mid-term elections, but they effectively canceled the political results of the election of President Obama by 69 million voters.
This tactic of inducing public distrust of government is not only cynical, it is schizophrenic. For people who profess to revere the Constitution, it is strange that they so caustically denigrate the very federal government that is the material expression of the principles embodied in that document. This is not to say that there is not some theoretical limit to the size or intrusiveness of government; I would be the first to say there are such limits, both fiscal and Constitutional. But most Republican officeholders seem strangely uninterested in the effective repeal of Fourth Amendment protections by the Patriot Act, the weakening of habeas corpus and self-incrimination protections in the public hysteria following 9/11 or the unpalatable fact that the United States has the largest incarcerated population of any country on earth. If anything, they would probably opt for more incarcerated persons, as imprisonment is a profit center for the prison privatization industry, which is itself a growth center for political contributions to these same politicians. Instead, they prefer to rail against those government programs that actually help people. And when a program is too popular to attack directly, like Medicare or Social Security, they prefer to undermine it by feigning an agonized concern about the deficit. That concern, as we shall see, is largely fictitious.
Undermining Americans' belief in their own institutions of self-government remains a prime GOP electoral strategy. But if this technique falls short of producing Karl Rove's dream of 30 years of unchallengeable one-party rule (as all such techniques always fall short of achieving the angry and embittered true believer's New Jerusalem), there are other even less savory techniques upon which to fall back. Ever since Republicans captured the majority in a number of state legislatures last November, they have systematically attempted to make it more difficult to vote: by onerous voter ID requirements (in Wisconsin, Republicans have legislated photo IDs while simultaneously shutting Department of Motor Vehicles (DMV) offices in Democratic constituencies while at the same time lengthening the hours of operation of DMV offices in GOP constituencies); by narrowing registration periods; and by residency requirements that may disenfranchise university students.
This legislative assault is moving in a diametrically opposed direction to 200 years of American history, when the arrow of progress pointed toward more political participation by more citizens. Republicans are among the most shrill in self-righteously lecturing other countries about the wonders of democracy; exporting democracy (albeit at the barrel of a gun) to the Middle East was a signature policy of the Bush administration. But domestically, they don't want those people voting.
You can probably guess who those people are. Above all, anyone not likely to vote Republican. As Sarah Palin would imply, the people who are not Real Americans. Racial minorities. Immigrants. Muslims. Gays. Intellectuals. Basically, anyone who doesn't look, think, or talk like the GOP base. This must account, at least to some degree, for their extraordinarily vitriolic hatred of President Obama. I have joked in the past that the main administration policy that Republicans object to is Obama's policy of being black. Among the GOP base, there is constant harping about somebody else, some "other," who is deliberately, assiduously and with malice aforethought subverting the Good, the True and the Beautiful: Subversives. Commies. Socialists. Ragheads. Secular humanists. Blacks. Fags. Feminazis. The list may change with the political needs of the moment, but they always seem to need a scapegoat to hate and fear.
It is not clear to me how many GOP officeholders believe this reactionary and paranoid claptrap. I would bet that most do not. But they cynically feed the worst instincts of their fearful and angry low-information political base with a nod and a wink. During the disgraceful circus of the "birther" issue, Republican politicians subtly stoked the fires of paranoia by being suggestively equivocal - "I take the president at his word" - while never unambiguously slapping down the myth. John Huntsman was the first major GOP figure forthrightly to refute the birther calumny - albeit after release of the birth certificate.
I do not mean to place too much emphasis on racial animus in the GOP. While it surely exists, it is also a fact that Republicans think that no Democratic president could conceivably be legitimate. Republicans also regarded Bill Clinton as somehow, in some manner, twice fraudulently elected (well do I remember the elaborate conspiracy theories that Republicans traded among themselves). Had it been Hillary Clinton, rather than Barack Obama, who had been elected in 2008, I am certain we would now be hearing, in lieu of the birther myths, conspiracy theories about Vince Foster's alleged murder.
The reader may think that I am attributing Svengali-like powers to GOP operatives able to manipulate a zombie base to do their bidding. It is more complicated than that. Historical circumstances produced the raw material: the deindustrialization and financialization of America since about 1970 has spawned an increasingly downscale white middle class - without job security (or even without jobs), with pensions and health benefits evaporating and with their principal asset deflating in the collapse of the housing bubble. Their fears are not imaginary; their standard of living is shrinking.
