Liberal Al Hunt at Bloomberg, here, bemoans the erosion of liberal Republicanism and hurls the "ideologue" epithet at conservatives:
'Movement conservatives are motivated by ideology, sometimes small-government economics, other times the religious social agenda. They range from Paul Ryan, the small-government, economic policy-savvy vice-presidential candidate, to Todd Akin, the Missouri Senate contender who last week suggested that it is rare for women to become pregnant as a result of rape, saying “If it’s a legitimate rape, the female body has ways to try to shut that whole thing down.”'
To a liberal Republican, apparently, preventing murder and national bankruptcy are unrealistic and idealistic causes.
Conservatives, on the other hand, are nothing if they aren't against ideology, and for life and economic solvency.
Conservatives define ideology as visionary speculation of an idealistic and unrealistic sort. They abhor notions of the perfectibility of man, and therefore also of man's social arrangements. They are not dreamy enthusiasts like President Obama who believes that "our union can be perfected."
Conservatives are ever mindful that human nature is a mixture of good and evil, and that just as self-government, the prerequisite of freedom, requires that human nature be checked by the individual's recourse to religion and morality to prevent sin and servitude, government above the individual level must also be limited by recourse to checks on its power to prevent crime and injustice. Above all, conservatives are mindful that there are no arrangements which will guarantee 100 percent success in these matters, only that some arrangements tend to work better than others, taught by long experience and reflection. They know that just because in the long run we are all dead doesn't mean there should be no speed limit signs.
It is a characteristic of liberalism to use intellectual categories like "ideology" not just to promote its (unrealistic) goals, but to attack its political opponents, after the manner of the Marxists who attacked bourgeois ideology. Nevermind that the bourgeoisie has hardly anywhere, ever been so self-conscious as even to think in ideological terms. But Barack Obama does, and self-consciously brings it up even when nobody else has: "I mean, that's my point, is that -- I am not an ideologue. I'm not." The term is left wing in its origin and development, and its continued use by liberals as an epithet and an intellectual category shows the close relationship between liberalism and the left which endures to this day.
This is who Al Hunt is, regrettably, and what liberal Republicanism is: an inherited thinly-veiled hatred of the middle class, which in its love of life and the enjoyment of its fruits stands in the way of the crackpots and schemers.
