the GOP's debt to McCarthy

Neal Gabler writes about "The GOP's McCarthy Gene" at the LA Times, refuting the faux-heroic Goldwater/Reagan myth of GOP ego-boosting:

...there is another rendition of the story of modern conservatism, one that doesn't begin with Goldwater and doesn't celebrate his libertarian orientation. It is a less heroic story, and one that may go a much longer way toward really explaining the Republican Party's past electoral fortunes and its future. In this tale, the real father of modern Republicanism is Sen. Joe McCarthy, and the line doesn't run from Goldwater to Reagan to George W. Bush; it runs from McCarthy to Nixon to Bush and possibly now to Sarah Palin. It centralizes what one might call the McCarthy gene, something deep in the DNA of the Republican Party that determines how Republicans run for office, and because it is genetic, it isn't likely to be expunged any time soon.

[...]

Republicans continue to push the idea that this is a center-right country and that Americans have swooned for GOP anti-government posturing all these years, but the real electoral bait has been anger, recrimination and scapegoating. That's why John McCain kept describing Barack Obama as some sort of alien and why Palin, taking a page right out of the McCarthy playbook, kept pushing Obama's relationship with onetime radical William Ayers.

And that is also why the Republican Party, despite the recent failure of McCarthyism, is likely to keep moving rightward, appeasing its more extreme elements and stoking their grievances for some time to come. There may be assorted intellectuals and ideologues in the party, maybe even a few centrists, but there is no longer an intellectual or even ideological wing. The party belongs to McCarthy and his heirs -- Rush Limbaugh, Sean Hannity, Bill O'Reilly and Palin. It's in the genes.
