Setting aside the notion that anyone to the left of Atilla The Hun is a limp willed "liberal" - which irrationally seems to underpin much of your posts, you take a good point but mix it with the biased observations and end up with at best a weak conclusion.
It is ALL ABOUT POLITICS in many ways. And Politics is about getting the power to get YOUR ideologies put into place.
So to that extent "intellectualism need not apply" has some near term logic to it. That is why extremely intelligent and well read individuals like Newt Gingrich, and yes Hannity do not worry about a reasoned discussion or putting forth a viewpoint that integrates all the facts. They are drawn to winning (some argue Hannity is just in it for the money) in the bloodsport of politics for whatever reasons motivate them.
But without a consistent foundation this leads to a hyper-opportunistic policy thrashing that people eventually catch onto, be it the Flip Flop by conservatives on the importance of Medicare - even now as they vigorously defend ALL of Medicare in the political arena, they invoke Medicare expansion as evidence of GWB's abandonment of conservative beliefs - or the hodgepodge internally contradictory "Acts" of the Contract With America.
And this is where intellectual underpinnings matter. And it is also where Conservativism AND your arguement go off the rails.
Yes Conservatives, having hamstrung Clinton and Gore's subsequent campaign with impeachment while hanging onto legislative majorities through gerrymandering other tricks of incumbency felt that "liberalism" had finally run out of intellectual steam.
And Yes, liberalism was having a tough time gaining POLITICAL traction in the face of a combination of 9/11 and dishonest political strategems like SBVFT. But Liberalism never actually abandoned its intellectual underpinnings. Yes the Politicians like Clinton stepped back from strongly advocating for it, but their core actions still were consistent with liberal intellectual ideals.
Where conservatives screwed up is that they equated political victory with a discreditting of the ideals themselves. Their own ideology blinded themselves to the fact that the USSR, and the PRC were nowhere near "liberalism" - and were in fact closer to "conservativism", and thus they felt they had won the intellectual debate as well. Yet the data to the contrary continued to pile up.
So contrary to current conservatives assertions as Gatewood does here... GWB did NOT "screw up" - at least not that massively and where he screwed up is not where you think he screwed up:
- Katrina - the Katrina disaster was a quintessential implementation of Conservative Ideals: regional autonomy, where the Federal Government has no business telling a state or city how to protect itself and until civil order breaks down, no proper role. According to Conservative Dogma, GWB's actions during Katrina WERE NOT A Screwup (politically yes, but not by conservative values)
- Afghanistan/Iraq - again Afghanistan was quintessential Conservative dogma - US Might allowing the flowering of local democratic aspirations but no "nation building" who cares if that means we lose Bin Laden. and Iraq was all about "Walk Loudly and Carry a Bigger Stick" militarism that Reagan and McCarthy posited so ardently
- Economic meltdown - Legislative deregulation (Gramm Leach Bliley) of financial markets straight out of Reagan's playbook, combined with further relaxing of existing regulations via "waivers" was 100% consistent.
- The explosion of the deficit - well this is Atwater/Gingrich/Laffer's "starve the beast" philosophy. Who cares if 1/3 of the tax cuts left the US economy
- Business Deregulation - "Clean Skies" iniatiatives FDA etc - what matters is the business lobby not the science
- NET Job Loss - deregulation of capital flows that allows for offshoring of jobs is quintessential conservative dogma
These are the big "screwups" of GWB. Yet each and everyone traces directly to the "intellectual" underpinnings of Conservative PHILOSOPHY. And this IS where "intellectualism matters" - because each of these dogmatic beliefs, PROVED THEMSELVES WRONG in the REAL WORLD.
Unlike Liberal ideals - which had a tough time in the face of less than honest political attacks, but which at their core have been proven as quite functional in much of the world, Conservative ideals failed IN THE REAL WORLD.
Liberalism did not need an intellectual revamping, it needed a better poltiical articulation.
Conservativism OTOH had great political articulation, but its core beliefs have been proven to be disconnected from reality.
And now the PT Barnum adage about all the people all the time comes home to roost. Without a redefinition of intellectual principles. the conservative leadership is left with that small permanent minority that are the "True Believers" for whom real world validation is unnecessary.
