Will Not Fillabuster Gonzales

After threatening to filibuster the Gonzales' nomination, implying they had enough support to do so -- Democrat Leader Harry Reid said "there will be an up-or-down vote". Now does this indicate they did not have enough votes, changed their mind, or simply can't agree on a course of action?

WASHINGTON - Democrats won’t try to filibuster Alberto Gonzales’ nomination to be attorney general but will hold extensive debates in the Senate over his role in developing the Bush administration’s policies on treating foreign detainees, the Senate’s top Democrat said Tuesday.
