Why so? My understanding of Frist's position is that there will be a vote on cloture. The vote is likely to fail. The vote on cloture will not mark the end of the fight, but merely the real beginning.
I take that to mean that after the cloture vote fails, the "debate" will assume 24/7 status. The Dems will be tested as to whether they can sustain an actual filibuster. Given the paucity of any legitimate argument against Estrada, this may prove difficult.
As a footnte, I would add that the winner of the filibuster battle will not depend on Frist per se , but on the 4 or 5 northern RINO Senators from the northeast. In other words, it comes down to a RINO vs. DINO fight-- just like all the other close issues that come before such an evenly divided Senate.
