Do you know if it's too late to rewrite the rules of the Senate to require an actual filibuster (Mr. Smith style) in lieu of the lame procedural filibuster currently employed? I would have no objection to a real filibuster; at least 5 Dems would vote for cloture after listening to Shrillary read from a phone book.
And if the constitutional option is invoked, I don't see the Dems plot to shut down the Senate lasting for very long. After a few days of doing nothing, I see a few of the reasonable Dems like Salazar and Lieberman and maybe some of their brethren, splitting off from the bloc. The Dems aren't a monolithic party and can't act as such for extended periods of time.
No, it's not too late-as long as you have 67 votes to do so.
That's what I'd like to see, real filibusters. With technology today, CSPAN feeds would be all over the internet. :=)
