Tribe is, unfortunately, rapidly backpedalling now - apparently not with any cogent explanation repudiating his prior position, but simply regurgiating the naieve collective view (veiled with an obligatory “oh, but it’s INDIVIDUAL”). Hints are his favorite law student - a certain B.H. Obama - may be seeking to return certain favors, involving a re-positioning on Heller.
Tribe or one of his students would be, of course, a likely candidate to replace the ailing and aging liberals on the Supreme Court.
I suppose you're aware that Tribe has been secretly lobbying the Justices for years, using his former students (the clerks) as intermediaries, discussing current research with them and suggesting references. So that an ingenuous new Associate Justice might send a clerk off to "see what you can find" on habeas, for example, and end up having an unsuspected and unlooked-for conversation with Professor Tribe instead, in the form of the clerk's returns of cites and quotes.
Tribe was also seen lobbying Justice Kennedy up close and personal for over three hours in a Viennese coffeeshop, on the eve of the Planned Parenthood case that revisited Roe.
Bob Novak wrote a column about all that, which turned into the perfect Buddhist stone tossed into a pool: zero splash, zero ripples, zero consequences.
The man is interfering with the cardinal lawmaking organ of the United States Government and getting away with it.
