I disagree strongly. What it did was perpetuate the "gentleman's filibuster", which has no place in a Constitutional Senate. Roberts and Alito would have survived a filibuster of the standard type, as the harsh light of the process revealed how baseless the Kennedy type attacks were. Instead, we got two USSC justices through without a real fight, but allowed the Dems to scuttle many, many more good appointments in the dark.
alito would not have, there would not have been 60 votes for cloture, and there would not have been 51 votes for a rules change. so he would have not been confirmed.
