Haynes Johnson just published a good one last week -- The Age of Anxiety: McCarthyism to Terrorism. While comparisons of BushCo to Tailgunner Joe are not particularly new or novel, Johnson really nails it:
McCarthy's Republican Party was far more moderate -- even liberal and progressive -- than the present Republican Party. Over the decades, a more rigidly ideological Republican Party has emerged, forged by many of the forces that McCarthy unleashed or harnessed. Out of McCarthyism came the modern conservative movement and the former liberals turned neocons who exercise their greatest intellectual and political influence today -- as seen in the major role they played in making the Bush administration's case for pre-emptive war against Iraq. McCarthyism was a major factor in the rise of the radical right and the polarization that plagues American of life, pitting group against group and region against region, sowing cynicism and distrust, and manipulating public of opinion through fear and smear. The so-called culture wars that afflict our public discourse are another of McCarthy's legacies, as is the continuing demonization of liberals, the national press, and others whose values are not of "real" and "patriotic" and church-going Americans.
Check it out if you get a chance -- you won't be disappointed.
