Although official transcripts of the oral argument in Lawrence vs Texas apparently will nor be available for 10-15 days, here is an unoffical transcript.
A numberof other comments have been posted to QueerLaw, the mailing list devoted to discussion of issues surrounding sexual orientation and the law (which I created in 1995 and still administer).
Both Evan Wolfson, the gay community's advocate in the Supreme Court case Dale vs Boy Scouts and E.J. Graff, a syndicated columnist who has been writing cogently about legal cases (mostly marriage-related) for years both think that Lawrence and Garner will prevail, either 6-3 or 5-4 (depending on whether we get both O'Connor and Kennedy). Graff's commentary (which also includes a pretty good summary of the oral argument) can be found at http://www.prospect.org/webfeatures/2003/03/graff-e-03-27.html
