we say "clued in" but i've never seen "queued in" used in that manner. a quick google search supports this assessment.
also: my guess is that this switch will have almost no legislative impact. first, specter will not regularly vote with the Dems on cloture votes.
second, the obama administration is too wimpy to supply the kind of legislation for which cloture votes matter.
on the other hand, this might help with judicial appointments and other senate advise-and-consent matters.
