Gregory's thoughts reminded me a lot of Justin Raimondo's take (h/t Jack Hunter):
'Part of what made this a signal event was that this was no pro forma type filibuster of the modern school, in which the Senator merely has to make known his or her intention to filibuster, but not actually get up there and speak. This was the real thing, and it was substantive. The Senate actually debated an important policy matter in the old style, with references to Shakespeare, and rhetorical flourishes the like of which we haven’t seen in many years. It was, in short, a paleo moment – and, politically, it was the Libertarian Moment, i.e. that moment in which a substantial body of Americans was rooting for a champion of liberty against the puffed-up conceit and criminal depredations of an overweening federal government...
What we are seeing is a seismic shift in the two parties’ approach to civil liberties, with the Democrats now freed to exude their inherent authoritarianism and the Republican grassroots in fear of a federal government headed up by a former "community organizer." Yet this isn’t just a matter of the partisan divide, although there is some of that: imbued with a sense that something has really gone wrong with the country, and disabused of the notion that the neocon-inspired dogmas of the Bush years are any kind of antidote, grassroots GOPers rallied to Rand‘s cause with sheer joy, like the inhabitants of a long-besieged city who see the cavalry coming over the hill.'
