"Ken" (whoever he is) is simply fact-impaired.
My preference for Root and Phillies was public before the convention. On May 8 I wrote (at http://more.libertarianintelligence.com/2008/05/advice-for-mary-ruwart.html): "I withhold judgment on Barr until he gets a lot more specific on what makes him a "100/100" libertarian and how sharply he plans to distance himself from his legislative record. My two favorite candidates so far are, in alphabetical order, Phillies and Root."
Other prominent reform-minded LP leaders backed Root even more strongly than I. For starters, I know that my fellow Californians Aaron Starr, Scott Lieberman, and Bruce Cohen advised the Root campaign. I don't think any of them were unhappy with Barr, but their preference was clear. Reform-minded radical (and recent Reform Caucus board member) Chuck Moulton voted for Root over Barr on the first five ballots, as he explains at http://lastfreevoice.wordpress.com/2008/09/11/voices-from-the-anti-barr-petition/#comment-29136. (He and I both voted for Kubby over Root for V.P., in hopes of balancing the ticket.)
Immediately after Denver, I publicly favored putting the Barr campaign on notice (especially regarding drugs and DOMA): http://libertarianintelligence.com/2008/05/clean-slate-not-blank-check.html
The history of the 2008 platform is told at http://libertarianintelligence.com/2008/06/birth-of-platform.html. It was assembled from past platforms on a Friday evening 14 months before Denver, and posted the next morning: http://groups.yahoo.com/group/LPplatform-discuss/message/1928. It's simply hallucinatory to claim that anything like the 2008 platform was "offered to the LNC as part of the improvement program then underway sometime in 2000".
Of course, with my magical Reformer powers to "rewrite LP history", I may have somehow fabricated all the above evidence after the fact.
