Voting in the Senate:
Forms and Requirements

Voting is among the most important public acts of individual Senators. For example,
Senators recognize that their decisions often need to be explained to constituents who are
interested in knowing why lawmakers voted as they did on various measures or matters.
Party leaders, too, understand the importance of voting, for they often try to schedule
votes during a time when they believe they can win senatorial support for their objectives.
That Senators try never to miss votes is reflected in the high percentage of rollcall votes
that they cast. On all recorded votes taken in the chamber, Senators, on average, cast
votes around 95% of the time.
There are three ways of voting in the Senate: voice, division, and yea and nay (also
called rollcall or recorded) votes. Neither voice nor division votes are recognized in the
rules of the Senate. Instead, they are permitted by precedent. Senate Rule XII outlines
voting procedure in the chamber and explicitly identifies “the yeas and nays.”
Voice Vote. On a voice vote, the presiding officer will first ask those in favor to
shout “aye” and then those opposed to say “no.” The chair may then say, “The ayes
[noes] appear to have it.” This announcement by the chair is not conclusive until the chair
declares that “The ayes [noes] have it.” Senators may ask for a division or rollcall vote
before the final result is announced by the presiding officer.
Commonly, the presiding officer will state, “Without objection the amendment [bill,
resolution, motion, etc.] is agreed to [or not agreed to].” This is simply another variation
of a voice vote. It does not imply that a single objection will defeat the proposition. Any
Senator may object, and the vote on the proposition will occur by one of the other
methods permitted by the Senate.
Division Vote. A division (or standing) vote is seldom used in the Senate.
However, any Senator, including the chair, may request a division if a Senator is in doubt
about a voice vote. A division vote does not provide a record of how each Senator voted;
it simply demonstrates whether a proposition, on which a division is requested, has been
approved or disapproved. As in the case of a voice vote, before the chair announces the
result of a division vote, a Senator may ask for the yeas and nays.

CRS-2
The results of either voice or division votes are considered valid no matter how many
or how few Senators actually participated in the vote. To be sure, the Constitution
requires a majority quorum — 51 of 100 Senators, if there are no vacancies — to be
present for the Senate to conduct business. As official precedents state, the Senate
“operates on the presumption that a quorum is present at all times, under all
circumstances, unless the question to the contrary is raised, or the absence of a quorum
is officially shown, or until a point of no quorum is made even though a voice [or
division] vote is taken and announced in the meantime.”
Yea and Nay Vote. Article I, Section 5, of the Constitution states that the “Yeas
and Nays of the Members of either House on any question shall, at the Desire of one fifth
of those Present, be entered on the Journal,” which is the official record of the
proceedings of the Senate. Thus, any Senator who obtains the floor may ask for the yeas
and nays (“I ask for the yeas and nays.”) on the question then pending before the Senate.
Immediately, the presiding officer will say, “Is there a sufficient second?” A sufficient
second consists of a minimum of 11 Senators who raise their hands, or one-fifth — the
constitutional standard — of the presumptive quorum of 51.
Sometimes a Senator will suggest the absence of a quorum to get sufficient Senators
to the floor to “second” his or her rollcall request. (“Mr. or Madam President, I suggest
the absence of a quorum.”) Once enough Senators reach the floor, the quorum call will
be dispensed with by unanimous consent and the request for a yea and nay vote will be
renewed. In practice, Senators who want a roll call vote on a proposition will almost
always receive sufficient support from their colleagues.
Quite often Senators will request and receive support for the yeas and nays on a
proposition in advance of the time that the vote actually occurs. A Senator, for example,
may offer an amendment and immediately ask for the yeas and nays. What this means is
that if the Senator’s amendment is subject to a vote — and not rejected on a procedural
motion, for instance — the vote will be by roll call. Ordering the yeas and nays on a
proposition does not imply that a vote on it is imminent. Debate on it may continue for
hours or days or weeks before the proposition is subject to a rollcall vote. Under Senate
precedents, ordering the yeas and nays may be rescinded by unanimous consent.
Conducting Rol call Votes. When it is time to conduct a rollcall vote, the
presiding officer will direct the clerk to call the names of all Senators in alphabetical order
and each member, as specified in Rule XII, “shall, without debate, declare his assent or
dissent to the question.” Following the call of Senators, the clerk will then recapitulate
the vote by first identifying those who voted in the affirmative and then those who voted
in the negative. Other Senators, who may wish to vote, go to the rostrum and respond
“yea” or “nay” when the clerk calls their names. A 15-minute period, which is established
by unanimous consent at the start of a Congress, is the time limitation for rollcall votes.
For instance, when the 110th Congress began, the Senate agreed by unanimous consent
that “for the duration of the 110th Congress, there be a limitation of 15 minutes each upon
any rollcall vote.” Sometimes votes are kept open beyond this period to accommodate
Senators who are hurrying to the chamber to cast their vote. If there are no Senators
waiting on the floor to vote, the presiding officer announces the result of the vote. Worth
noting is that the Senate, unlike the House, does not permit electronic voting.
