There are not more conferences, but the controversy in the conferences is greater than has been in past years. The budget resolution, the energy bill, the Medicare bill, and the defense authorization bill – each considered this year – have had protracted, contentious conferences. More on that in a minute.
I’ll answer number three next for clarity’s sake:
The appointment of conferees is pretty much a routine, housekeeping measure taken up independently in both the House and the Senate. It is extremely rare that there is any debate or actual votes on appointing conferees.
In the Senate, generally the membership of the committee of jurisdiction is automatically appointed as conferees. In the House, the top “x” members of the primary committee of jurisdiction is generally appointed (because committees in the House are so large), and “outside conferees” may be appointed from among the other House committees that share jurisdiction. In either case, the ratio of Republicans to Democrats is generally the ratio represented on the committees of jursidiction, so that there will always be more of the majority party represented in the conference deliberations.
As Sofa King points out, the Chair of a conference committee can sometimes act like a jerk and be a terrible partisan weenie.
brianmelendez had it right. The actual functioning of the conferences vary - ie, some conferences hold votes of each Body to resolve an issue (ie, the Senate conferees will vote on whether to recede – or agree to – to a House provision). Others leave it up to the Chairmen and Ranking Members of each Body in the conference (a group sometimes called “The Big Four”) to work out an agreement and then seek the approval of the other members of the conference.
And reference Sofa’s comment about legislative provisions inserted during conference, Senate Rule 28 establishes a point of order against a conference report (that is, the compromise bill approved by a conference committee) that contains matter that was not addressed in either a House or Senate bill. It is a powerful tool frequently used to keep extraneous matter from being added in conference.
(And in regards to the Boeing tanker lease issue, it is not actually a good example of a so-called “virgin birth,” because the House bill contained provisions on the lease which were modified in the conference. I must disagree with Sofa’s otherwise astute commentary.)
