Many credit Ronald Reagan (and I think rightly so) with building the "3-legged stool" that is the modern conservative movement. The three legs being Defense Conservatives, Fiscal Conservatives, and Social Conservatives.
Rush Limbaugh needs to realize his own marginalizing of moral and social issues (at the root of his attacks on Mike Huckabee) is in danger of cutting off the Social Conservative leg. A leg that the leaders of the Republican party have been doing little beyond rhetoric to shore up in recent years.
I think there are two basic reasons Rush is attacking Mike Huckabee. Number 2 is that Huckabee does, admittedly, often lead with a populist sounding attention getter up front and one often has to sift for his solutions; which ARE CONSERVATIVE.
The Number 1 Reason is the one area where RUSH IS NOT CONSERVATIVE. Rush strikes me as having become too much of a hedonist (or at least giving a wink to hedonism) to be able to support anyone who takes issues like fighting homosexual mainstreaming seriously. As one who has listened to Rush for years, it's obvious that he thinks homosexual mainstreaming is no big deal. For me, it's the biggest.
We can recover from a temporary tragic bout of liberalism in fiscal areas. All but the most extreme far-left liberal loons become "Defense Conservatives" when our nation is obviously threatened. But a governmental sanction of homosexual practice would shatter our basic culture to such a degree that we would never recover.
Huckabee needs to put his conservative solutions more up-front in his speeches and answers. This would help put those at ease who, after hearing Rush's false charges that Huckabee is liberal in the Defense and Fiscal areas; and may not look deep enough into his record and statements to see Huckabee's firm support for all three legs.
Although it's apparent that Rush does believe in God as the Creator (see his "Undeniable Truths of Life" #s 20&23); he seems to worship at the altar of the "Almighty Dollar" first and foremost, and seems incredulous that any candidate mentions any subject more often than money.
Rush has enough staff and history of deep research that he either knows his charges are false, or he is predisposed to believing the worst about a candidate who is dedicated to supporting the Conservative stool by three firm legs even if he has carve a replacement for the fragile Social/Moral leg himself from a tree of basically Biblical values. I have enough reason not to doubt Rush's honesty that I believe it's the latter, and therefore he simply hasn't bothered to get all the facts about Huckabee.
In either case, it seems to indicate Rush believes more in a stool supported by two legs and a broom-straw, than the 3-legged stool of Ronald Reagan. [note (2008-01-03): My opinion of Rush's intention have changed after a statement Rush made the night of the Iowa caucus. I now think he believes Huckabee would be very likely defeated by the Democrats, and his loss would marginalize "the Christian right." Look for a more in-depth post on that subject later today.]
