Given the constant "compromise" noises from the New York Times and liberal talking heads (mainly because the Democrats can't stop the rule change if it comes up), I'm betting the Democrats will step back from the brink and allow the cloture motion on Priscilla Owens to pass. This will maintain the filibuster for later (well, at least until next week). The Dems can talk about delaying Owen's appointment for several years, as a matter of Principle, while allowing an up-or-down vote in the end. My guess is something like 62-38.
The real question is whether this will allow them to continue other filibusters, making the argument that the rule change isn't needed because they're only filibustering a few judges -- giving cover to Senators like Specter to "defend Senate rules."
